Adafruit PN532 NFC/RFID Controller Shield for Arduino + Extras – We’ve taken our popular Adafruit PN532 breakout board and turned it into a shield – the perfect tool for any 13.56MHz RFID or NFC application. The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) and is what is embedded in pretty much every phone or device that does NFC. It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and ‘act’ like a NFC tag. If you want to do any sort of embedded NFC work, this is the chip you’ll want to use!
NFC (Near Field Communications) is a way for two devices very close to each other to communicate. Sort of like a very short range bluetooth that doesn’t require authentication. It is an extension of RFID, so anything you can do with RFID you can do with NFC. You can do more stuff with NFC as well, such as communicate bi-directionally with cell phones
Because it can read and write tags, you can always just use this for RFID-tag projects. We carry a few different tags that work great with this chip. It can also work with any other NFC/RFID Type 1 thru 4 tag (and of course all the other NXP MiFare type tags)
The Adafruit shield was designed by RF engineers using the best test equipment to create a layout and antenna with 10cm (4 inch) range, the maximum range possible using the 13.56MHz technology. You can easily attach the shield behind a plastic plate with standoffs and still read cards through a (non-metal) barrier.
This shield is designed to use I2C or SPI communication protocols. I2C is the default, as it uses fewer pins: analog 4 and 5 are used for I2C (of course you can still connect other I2C devices to the bus). Digital #2 is used for “interrupt” notification. This means you don’t have to sit there and ‘poll’ the chip to ask if a target tag has been found, the pin will pull low when a card, phone, etc is within range. You can adjust which pin is used if you need to keep digital #2 for something else. It is also easy to change the shield over to SPI where you can use any 4 digital pins by shorting two solder jumpers on the top of the PCB. Compatible with any “classic” Arduino – NG, Diecimilla, Duemilanove, UNO – as well as Mega R3 or later. For using the I2C interface with Mega R2 or earlier, two wires must be soldered as the I2C pins are in a different location on earlier Megas.
Tagstand, a startup which helps companies integrate NFC tags into products and events, threw a massive cocktail party in New York to show off their capabilities. While details of the tech are sparse, from the picture above, it appears that Tagstand used the Adafruit PN532 NFC/RFID controller breakout board powered by an Arduino.
[Tagstand] will see its technology used to enable some nifty actions for the 3,500 guests, like tapping to tweet, posting pictures to Facebook and registering “likes” for the cocktails they’re drinking. Sounds like (kind of geeky) fun!
The event in question is New York’s big cocktail party for the opening night Gala at The New York Public Library, which is offering up 30,000 different cocktails, created by over 150 different bartenders. (Now you can see why “liking” a particular cocktail might come in handy – that’s a lot to remember.) In fact, after a guest likes a cocktail, they’ll be able to receive the drink recipe via a personalized email courtesy of foodie guide Tasting Table.

Near field communication (NFC) technology enables smartphones to work with mobile payments and public transit systems, but a new accessory from Sony could make the wireless wonder much more personal.
SmartTags are small programmable tokens that give your NFC-equipped Android phone a series of commands to keep you from performing repetitive tasks.
For example, swiping your phone by a SmartTag placed on a nightstand could turn your phone silent, turn off Wi-Fi/Bluetooth, and activate your alarm for the following morning. While the aforementioned tasks are easy to do on your own, perhaps there is a certain charm in an automatic trigger.

Online payments enabler PayPal today unveiled its first NFC (near-field communication) solution for Android devices at the MobileBeat 2011 conference in San Francisco.
Laura Chambers, senior director of PayPal Mobile, showed off how PayPal’s new NFC Android widget can be used to transfer money simply by tapping together two Nexus S phones.

Eric Schmidt, Google’s executive chairman, believes that a third of check-out terminals in retail stores and restaurants will be upgraded to allow wireless “tap and pay” from mobile phones within the next year. Such a development will prepare the ground for what he believes will be a “trillion dollar” industry of mobile advertising and payments.
It won’t be in “most” places within a year, but it will be in high traffic places like Starbucks seemingly overnight. At this time Starbucks scans a QR-looking code with their current scanners which uses an app on the iPhone, but as soon as iPhone gets NFC we think Starbucks will add that at the same time, likely a joint-keynote thing with Jobs and Shultz. Android (Google) has the Nexus S with NFC and Google announced Google wallet, but it’s not slated to be out until “summer”. As of last week there is an official “scan the screen” app for Android too for Starbucks.
This is a little hack that allows very low bandwidth communications in one direction for practically no cost. It’s not practical for most applications, but I thought the idea was sufficiently interesting to explore. This article describes how to implement a very low bandwidth one way communication channel between an Arduino (or any other microcontroller) and an Android device using nothing more than about a meter of magnet wire, a resistor and diode. Links to a software sketch for the Arduino and the Android source code is included.
In the setup, a participant wore a backpack containing a laptop and a data acquisition device connected through a wire to a conductive pad on the back of the participant’s neck. The pad measured the voltages picked up by participants, who performed specific gestures around light switches. Software in the laptop generated positioning instructions and at each switch, the gesture order was randomized to eliminate bias.
The experiments showed that electromagnetic noise is so predictable that it can be used it to figure out where a person is standing, what the person is doing, and even where a hand is placed on a wall. The team used a simple sensor that was essentially just a piece of metal, but Morris said that ultimately a sensor could be placed in the user’s hand or anywhere else that the radio signals being picked up by the body can be gathered.
“Our bodies, it turns out, are actually really good and relatively colorful antennas,” Morris said. The team presented their results earlier this week in Vancouver at the ACM CHI Conference on Human Factors in Computing Systems.
The researchers learned that in a typical house, the electromagnetic noise changes noticeably from room to room because of the various appliances in them. Then they applied artificial intelligence to the data.
“The noise is different enough in those different environments that the computer can actually use machine learning to tell the difference,” Morris said.
