As with many things related to the Rams this season, the crowd and I were both wrong: Bradford was healthy enough to make his way back on to the active roster in January, and while injuries are perennially a concern for the draft's No. Two of those games came during the final two weeks of the season. To be fair, Tampa's cornerbacks didn't get any help from the defensive line, which produced a league-low sack rate 3.

Work with supported tag technologies

Five moves all 16 NFC teams should make this offseason

A patent licensing program for NFC is under deployment by France Brevets, a patent fund created in This program was under development by Via Licensing Corporation, an independent subsidiary of Dolby Laboratories , and was terminated in May Present and anticipated applications include contactless transactions, data exchange and simplified setup of more complex communications such as Wi-Fi.

NFC is rooted in radio-frequency identification technology known as RFID which allows compatible hardware to both supply power to and communicate with an otherwise unpowered and passive electronic tag using radio waves. This is used for identification, authentication and tracking. NFC operates at NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target. This enables NFC targets to take very simple form factors such as unpowered tags, stickers, key fobs, or cards.

NFC peer-to-peer communication is possible, provided both devices are powered. NFC tags contain data and are typically read-only, but may be writeable. They can be custom-encoded by their manufacturers or use NFC Forum specifications. The tags can securely store personal data such as debit and credit card information, loyalty program data, PINs and networking contacts, among other information. The NFC Forum defines four types of tags that provide different communication speeds and capabilities in terms of configurability, memory, security, data retention and write endurance.

Tags currently offer between 96 and 4, bytes of memory. As with proximity card technology, near-field communication uses electromagnetic induction between two loop antennas located within each other's near field , effectively forming an air-core transformer. It operates within the globally available and unlicensed radio frequency ISM band of Theoretical working distance with compact standard antennas: Note because the pickup antenna may be quenched by nearby metallic surfaces, the tags may need to be spaced slightly away from the surface.

NFC employs two different codings to transfer data. NFC devices are full-duplex—they are able to receive and transmit data at the same time. Thus, they can check for potential collisions if the received signal frequency does not match the transmitted signal's frequency. Applications may use higher-layer cryptographic protocols e. SSL to establish a secure channel. The RF signal for the wireless data transfer can be picked up with antennas.

The distance from which an attacker is able to eavesdrop the RF signal depends on multiple parameters, but is typically less than 10 meters. A passive device that doesn't generate its own RF field is much harder to eavesdrop on than an active device.

An attacker can typically eavesdrop within 10 m and 1 m for active devices and passive devices, respectively. This is similar to a man-in-the-middle attack.

This attack can be implemented using only two NFC-enabled mobile phones. These standards specify the modulation schemes, coding, transfer speeds and frame format of the RF interface of NFC devices, as well as initialization schemes and conditions required for data collision-control during initialization for both passive and active NFC modes.

They also define the transport protocol , including protocol activation and data-exchange methods. The air interface for NFC is standardized in:. NFC-enabled phones work at a basic level with existing readers. In "card emulation mode" an NFC device should transmit, at a minimum, a unique ID number to a reader. The GSM Association GSMA is a trade association representing nearly mobile telephony operators and more than product and service companies across countries.

Many of its members have led NFC trials and are preparing services for commercial launch. Standards include the four distinct tag types that provide different communication speeds and capabilities covering flexibility, memory, security, data retention and write endurance. NFC Forum promotes implementation and standardization of NFC technology to ensure interoperability between devices and services.

HCE allows any Android 4. NFC offers a low-speed connection with simple setup that can be used to bootstrap more capable wireless connections. The Ameer Abdullah experiment just hasn't taken.

Lions fans might still have fond memories of Abdullah's preseason exploits as a rookie, but the Nebraska product has only been healthy enough to carry the ball times over three seasons, and he has averaged 3. Among backs with carries or more over the past three years, Abdullah's With the Lions hiring Patricia and assuming their new role as New England Midwest, there are a bevy of ex-Patriots running backs due to hit the market this offseason. I'm guessing Dion Lewis will return to New England.

Given Theo Riddick 's skill set, we can rule out Shane Vereen. Stevan Ridley is roster fodder. LeGarrette Blount played a meaningful role for most of the year in Philadelphia, but he probably would be strictly a short-yardage back here. One back who does fit, though, is Rex Burkhead. The former Bengals backup didn't carve out a consistent role thanks to injuries, but the Patriots were able to both use Burkhead as a traditional running back and split him out against overmatched linebackers in coverage.

The Lions already do that with Riddick. Burkhead would give Stafford another intermediate target and a back capable of running over defenders. Extend Aaron Rodgers ' contract. Kirk Cousins ' free-agent contract is going to reset the quarterback market, possibly in a drastic way. The Packers, who are going to re-sign Rodgers either this offseason or next, would be smart to get an extension done with their future Hall of Fame quarterback before Cousins signs his deal. Rodgers will and should ask for more.

This is probably the last big deal Rodgers will sign, and while there's no way he's leaving Green Bay, the Packers are going to pony up for the best quarterback in franchise history. Both sides should want the Nelson-Packers relationship to continue onward for a few more seasons.

Nelson slipped badly last year without Rodgers in the lineup, which might dissuade the year-old from looking elsewhere in free agency next season and encourage him to take yet another discounted offer. Ask Randall Cobb to take a pay cut and release him if he declines. If that happens, though, the Packers are probably going to be down a slot receiver.

Cobb is entering the final year of his own extension, and while he's nearly five years younger than Nelson, the year-old has failed to deliver on the 1,yard season he posted in advance of free agency in His yards per reception and receiving yards per game have dropped in each of the past three seasons. The problem for Cobb is that he would be entering a market that may not be very excited to see him. Someone is going to want Cobb, but it might not be for more than a one-year deal.

Given that possibility, Cobb might be better off taking a pay cut and playing his final year in Green Bay with Rodgers. Add a tight end in free agency. While just about everyone was in favor of the Packers signing Martellus Bennett last offseason, the well-traveled tight end lasted half a season in Green Bay before leaving under a cloud of injury-related controversy. Green Bay's leading receiver at tight end was Lance Kendricks , who had the second-highest drop rate in the league among tight ends with 30 targets or more.

The position is still a hole for the Packers. Let's try to address that this offseason. There are a bevy of useful tight ends in the marketplace. Selfishly, I'd like to see the Packers sign Tyler Eifert just to see if we can get 14 healthy games of Rodgers throwing to Eifert in the red zone. Jimmy Graham is available. Someone is going to give Trey Burton No. And hey, if Rodgers gets hurt again, we know Burton can pass Upgrade at backup quarterback.

In all seriousness, though, the Brett Hundley experience was not fun. McCarthy wasn't willing to overwrite his offense and play to Hundley's strengths, which led to weeks of checkdowns and punts. Rodgers probably isn't going to miss nine games again, but he's getting older and has missed at least one game in four of his 10 seasons as a starter. The Packers aren't going to find anyone on earth who can do what Rodgers does, but someone they trust to throw the football would be nice.

Mike Glennon didn't work as a starter in Chicago, but he's qualified to serve as a backup and had at least some modest success during stretches in both Chicago and Tampa Bay. With the Vikings losing offensive coordinator Pat Shurmur to the Giants, new offensive coordinator John DeFilippo will inherit a quarterback coming off the season of his life.

One thing is for sure: The Vikings could let Keenum move on, possibly also to New York, but giving Keenum away after a season where he might have been one of the best quarterbacks in football for a possible comp pick just seems shortsighted. So, should the Vikings franchise him or lock him up to a long-term contract? Franchising Keenum allows the Vikings to get away if Keenum's was a mirage, but it also possibly locks the Vikings into the Cousins Cycle, where their quarterback rightfully feels disrespected and it ends up torpedoing the franchise.

That deal was essentially a one-year pact with the ability to trigger a multiyear extension after the initial campaign. That structure would allow the Vikes to hand Keenum a raise and set up a possible long-term commitment without locking them in if Keenum declines. If Cousins wants to win right away, there's no better landing spot for him on the free market than Minnesota.

The Vikings have a perennially great defense and a running game that should be better next year with the return of a healthy Dalvin Cook. They're deep with weapons, and with Adam Thielen signed to a steal of a four-year deal, the biggest weapon isn't going anywhere. As much as it would hurt to move on from Keenum, and as much as you'll hear about how Mike Zimmer wants to build around his defense, you don't pass up on Cousins.

The Vikings can create more space in by signing Barr to an extension. GM Rick Spielman would likely bring that number down as part of an extension. Valuing Barr will be tough. The year-old made his third straight Pro Bowl this season, and his range as a thumping linebacker is unquestioned.

At the same time, though, front-seven pieces get paid for their ability to rush the quarterback, and while Barr very famously ruined Aaron Rodgers' season, he's not really a pass-rusher.

Barr finished with one sack and four quarterback knockdowns this year, and his sack totals have dropped in each of his four pro seasons. Mike Zimmer doesn't really use Barr as an edge rusher, so he might rack up better numbers on a different team, but the stats are the stats. If they give Barr a big deal, though, that probably means moving on from Eric Kendricks after With Kendricks, Diggs, Hunter, Barr and possibly Trae Waynes all due to become free agents next offseason, Minnesota will have to make some tough choices in the near future.

While Sproles was expected to retire after the season, reports during Super Bowl week suggested that the year-old wanted to come back and finish his career on his terms after missing most of the season with a torn ACL. The Eagles found a useful replacement for Sproles in Corey Clement , though, and it seems likely they won't bring back the pint-sized dynamo in Enter the Vikings, who have a need for a receiving back behind Cook and Latavius Murray.

Jerick McKinnon is a free agent and likely to receive a larger deal than the Vikings are going to offer for a strict third-down back, but Sproles would fit on a one-year deal. Add defensive tackle depth in the draft. The Vikings are suddenly thin at defensive tackle.

Sharrif Floyd is likely done playing because of a nerve issue in his knee, and the Vikings will likely waive him with an injury designation this offseason. Tom Johnson is a free agent and in line for a raise, while backup Shamar Stephen is also a free agent.

Linval Joseph and fourth-rounder Jaleel Johnson are in the mix, but the Vikings should be looking at defensive tackles with their selections in the first two rounds of the draft. No team was more aggressive about acquiring talent in as many different ways over the last year than the Eagles. Even after moving up in the draft to grab Carson Wentz in , Howie Roseman refused to stay put and continued to reshape the roster around Wentz.

You know what happened next. In the end, Philadelphia's decision to move on from backup quarterback Chase Daniel and bring back former starter Nick Foles might have ended up as its most important call.

A move that was an afterthought amid a busy offseason ended up helping the Eagles win their first Super Bowl. Dallas' star guard is entering the fifth and final year of his rookie deal, and the Cowboys will almost surely give the former Notre Dame star one of their patented eight-year contract extensions. Martin likely will become the highest-paid interior lineman in football when he signs his deal. Restructure Travis Frederick 's deal. The Cowboys might not be as aggressive to clear out cap space by restructuring Tyron Smith 's deal, given that their star left tackle battled myriad injuries this season.

Frederick is one of the best centers in the league and isn't going anywhere, so the Cowboys will be more comfortable clearing cap space with the Wisconsin product. Force Dez Bryant to take a pay cut or release the year-old. While you might have blamed injuries for middling seasons from Bryant in and , he played all 16 games this season and wasn't able to consistently change games.

His line wasn't dissimilar to the line posted by Jermaine Kearse , who was essentially a throw-in for the Jets in the Sheldon Richardson trade. At this point, the dynamic downfield receiver who terrified defensive backs from to '14 looks to have been replaced by a possession target who primarily leverages his size to win on slants.

From to '14, Dez was 31st among wideouts in average yards after catch and caught 31 passes on throws more than 20 yards downfield, the sixth most in football. Bryant had just 11 such catches over the three ensuing seasons, including just four in He was 63rd in yards after catch over that time frame. Bryant still has a role to play on this team, but he's years removed from performing like a No. If the three-time Pro Bowler doesn't improve, though, this will be Dez's last year in Arlington.

The Cowboys can use the money they save from the previous deals to free up room to bring back their star defensive end. Should the Cowboys sign Lawrence to a long-term deal now? It depends on the price. Lawrence took an enormous leap in , racking up Over 25 games in and '16, Lawrence generated nine sacks on 18 hits. Lawrence hasn't shown enough to get paid like a guy who is perennially going to reach double-digit sack totals, but if he hit the free market, some organization would see a year-old coming off a Pro Bowl season and back up the Brink's truck to sign him.

The franchise tag keeps Lawrence off the market and gives the Cowboys leverage as they negotiate a new deal. Pick up Byron Jones ' fifth-year option and pick a place for him to play. This season was a step backward for the former first-round pick. Jones' versatility should be an asset, but defensive coordinator Rod Marinelli seemed to get frustrated with Jones' lack of consistency and eventually started taking him out of the lineup for sixth-rounder Kavon Frazier , who carved out a bigger role with some big hits as an in-the-box strong safety.

Jones was expected to be a project coming out of UConn, but Dallas hasn't helped his development by moving him from cornerback to safety.

It seems pretty clear that Jones isn't a strong safety. He should have the athleticism to play center field as a free safety, but the Cowboys don't appear to love Jones in that role.

Assuming that the Cowboys keep Xavier Woods in the slot and move on from Orlando Scandrick , Jones could play ahead of Jeff Heath at free safety in if the Cowboys want to give him a shot there. What about moving him back to cornerback and keeping him at his old position? New defensive backs coach Kris Richard had plenty of success working with big, physical cornerbacks during his time in Seattle, which should help the 6-foot-1, pound Jones. Maybe Jones profiles as a guy who can play in coverage against the division's tight ends, a group that includes Zach Ertz , Evan Engram and Jordan Reed.

Under any circumstance, the Cowboys need to find out what they have in Jones in Announce that this will be Eli Manning 's last season in a Giants uniform. When the Giants shockingly benched Manning in November , I rued the missed opportunity to treat their longtime starting quarterback with some class.

After firing virtually everyone involved with the decision short of ownership, they can get a redo here. Manning slipped badly between and , although the success of the defense during a playoff year masked his decline. Manning has to leave the team eventually, but send him out in a way everyone will find satisfying.

Treat it like a graduation. Ask Eli how he wants to handle things. Announce an Eli Manning Day for one of the home games in September or October and bring guys from the and teams back to celebrate. Just don't offer to string together a start streak for no reason. Draft a quarterback with the second overall pick.

The Giants have to replace Manning over the next two to three years. They hired Pat Shurmur in the hope that he was going to develop their next franchise quarterback. You only get a few chances at drafting or acquiring that guy, and while the Giants would probably rather have their pick of the draft crop at No. Whom should they take? It's still too early to say.

Honestly, whom they take is probably less important than what they do to support their new passer. Shurmur helped mold Foles in Philadelphia and manufactured a career year from Case Keenum in Minnesota, so while he struggled with game management during his time as a coach with the Browns, his recent track record looks promising.

If the Giants keep Manning, there will be no reason to rush their new pick into the lineup. They can play Manning if he plays well and the Giants stay competitive. If they struggle, there will be an opportunity to bring on their new quarterback later in the year, although I'd recommend they handle it with far more grace than the organization did this season.

Re-sign Odell Beckham Jr. Last year, the timing didn't make sense for the Giants to re-sign Beckham. He was too much of a bargain for too many years to come to rip up his deal and make him the highest-paid wideout in football, let alone give him the sort of quarterback money Beckham publicly sought.

Beckham's broken ankle basically cost him all of , but it shouldn't impact the year-old's long-term outlook. He's one of the best wideouts in the league and should be for the next several years. It would be smart for the Giants to get ahead of the curve and sign Beckham to a new deal before the cost of signing wideouts goes up any further. Jarvis Landry is a free agent now, but Beckham's free-agent class next offseason would include the likes of Stefon Diggs and Mike Evans.

Those guys likely aren't going to make it to free agency, but Beckham and Evans are going to reset the wideout market. If Beckham signs first, Evans will get slightly more, and vice versa.

The Giants probably want to beat the Bucs to the punch. What would get a deal done? Beckham is going to top those both marks, but it's a question of how much he'll get on top of what Hopkins earned. The deal might be structured differently, but the general concept should be the same: Beckham will get a record deal for a wide receiver by one definition or another.

The Giants will also need to sign Landon Collins , but it seems more likely that they franchise their star safety in before signing him to an extension next year. Clear out cap space. Improve the offensive line. The Eagles just won their first Super Bowl with a dominant performance from their offensive line.

The Giants have generated the league's third-worst rushing average and its worst first-down percentage on run plays thanks to a horrific offensive line. The Giants desperately need to protect whichever quarterback will be starting for this team in and beyond. They're not doing that with Ereck Flowers at left tackle.

Things need to change, and the Giants' two best offensive linemen -- center Weston Richburg and the versatile Justin Pugh , who has lined up at left guard, right tackle and even left tackle during his career -- are both unrestricted free agents.

Starting right tackle Bobby Hart was waived by the team at the end of the season and wasn't claimed by any other teams, which should be telling. The obvious move would be for Gettleman to sign Panthers guard Andrew Norwell , who is likely to leave after Carolina locked up fellow guard Trai Turner with an extension. The Giants desperately need to upgrade on Flowers, whose fifth-year option is likely to be declined. There's little guarantee Flowers will be better on the right side , but the Giants can't trust him to protect the blind side of their quarterbacks at this point.

They can try to draft a left tackle with their second-round pick or trade up into the first round , but the best solution might be to re-sign Pugh to play right tackle and use Rhett Ellison more frequently to give Flowers help on the left side.

Decline Torrey Smith 's option. The former Ravens standout had a frustrating debut season in Philadelphia, with rookie fourth-rounder Mack Hollins taking some of Smith's snaps as the season went along. Designate Jason Peters as a post-June 1 release.

Peters is one of the few exceptions, and Halapoulivaati Vaitai showed enough improvement during the season for the Eagles to turn a starting job at tackle over to their swing tackle. Explore the trade market for Nick Foles.

I mentioned this in my Super Bowl recap , but the Eagles should operate from a position of strength with Foles given the uncertainty surrounding Carson Wentz 's knee.

The Eagles don't need to trade Foles, and if they don't get a great offer, they should hold on to him for another year. If a team like the Bills or Jets offers the Eagles one of its second-round picks for Foles, it might be a good opportunity to sell high on a player who isn't going to supplant Wentz in the long term and will hit free agency in It wouldn't be a surprise to see veterans who are chasing a ring like McCown head to Philadelphia for smaller-than-expected deals this offseason.

Wait out the market on Nigel Bradham. Bradham, nickel safety Corey Graham and slot cornerback Patrick Robinson are all free agents this offseason. Robinson played well enough to earn a deal Philadelphia can't match, and the Eagles seem heavily committed to cheap cornerback play given their investment along the defensive line and at safety. Graham might be back. Bradham will be an interesting situation. The Eagles used the former Bills linebacker and Mychal Kendricks as their every-down linebackers after Jordan Hicks tore his Achilles early in the season.

Bradham is a better player than Kendricks, but the Eagles can't really commit another multiyear deal to a linebacker given how much they've spent elsewhere on their roster. If the market for Bradham doesn't develop, though, it wouldn't be crazy to see the year-old return to the Eagles on a short-term pact.

Re-signing Bradham would probably bring Kendricks' time with the Eagles to a close. Trade down on draft day. The Eagles are missing second- and third-round picks from various trades, and while they have an extra fourth-round selection, they'll need to replenish some of the missing depth from the Wentz trade and add cost-controlled talent to develop behind their core.

Teams love trading up to the final few picks of the first round, since it allows them to acquire a possible fifth-year option for a player they were already planning on taking with one of the top few selections of the second round. Philadelphia has pick No. Resist the urge to franchise Kirk Cousins. Trading for Alex Smith should have brought an end to the Cousins era in Washington , and while you can understand the organizational desire to get something back for their franchise quarterback, that ship sailed a year ago.

Why would Cousins want Washington to narrow his options, and why would he want his new team to give up valuable draft picks as a thank-you to the franchise that is moving on from him? Let's say Cousins wants to go to the Broncos. General manager Bruce Allen might very well go to Denver and threaten to franchise Cousins in the hopes of extracting a draft pick, but he has zero leverage. Denver will happily wait for Cousins to eventually hit the market, which will happen after Washington releases Cousins.

It's a desperate bluff from Washington. Cousins is a sunk cost at this point. Washington can get a third-round compensatory selection in the draft when Cousins signs elsewhere, but the comp pick isn't guaranteed. Washington can nullify the selection by investing in free agency, either by going after a top-tier talent or a handful of cheaper players. The latter strategy will prevent the Bills from picking up a compensatory pick for Stephon Gilmore this year. Obviously, compensatory picks can be valuable, and free agency can often be a fool's errand, especially for Snyder.

What I don't like is the idea of sitting out free agency and ensuring a compensatory pick just so Washington can sit there and say it got something back for Cousins.

That's a PR move, not a football decision. Those third-round compensatory picks also haven't delivered many stars in recent years. Here are the players drafted with third-round comp selections over the past 10 drafts:.

Chad Rinehart, Andre Caldwell, Thomas DeCoud, Oniel Cousins It's still too early to evaluate some of the more recent classes, but these guys combined for all of one Pro Bowl appearance, and that was from DeCoud, who was drafted a decade ago. Adding a compensatory pick is a smart move, but sitting out free agency specifically so Snyder can say five years from now that he got a second tight end or a subpar offensive lineman as compensation for Cousins isn't the right football decision for this franchise, especially after trading for a year-old starting quarterback.

Re-sign Zach Brown and Spencer Long. You can use the getTechList method to determine the technologies supported by the tag and create the corresponding TagTechnology object with one of classes provided by android. Having this fallback allows you to work with the data on the tag directly if the tag dispatch system could not parse it for you.

The basic steps when working with tag technologies are as follows:. Reading and writing to an NFC tag involves obtaining the tag from the intent and opening communication with the tag. You must define your own protocol stack to read and write data to the tag. Keep in mind, however, that you can still read and write NDEF data when working directly with a tag. It is up to you how you want to structure things.

The foreground dispatch system allows an activity to intercept an intent and claim priority over other activities that handle the same intent. Using this system involves constructing a few data structures for the Android system to be able to send the appropriate intents to your application.
