Here’s an elaborate NFC Raspberry Pi project-in-progress from HubCityLabs in New Brunswick:
Over the past few weeks, we at HubCityLabs have been busy! We’ve started work on a project will let us control access to our facilities with NFC cards, and later on, bio-metrics. Since for each access point, there will be multiple readers (NFC, fingerprint, retina scanners…) for each host (a RaspberryPi), we settled on using I2C as a standard for communication between the host and the peripherals. Our chosen language was Python, since it seems to be the de-facto language on the RaspberryPi….

PN532 NFC/RFID controller breakout board – v1.3: The PN532 is the most popular NFC chip, 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)… (read more)
