Tutorial: RFID tags with the NXP NFC controller PN7120 and Eclipse
Erich Styger writes: Playing with RFID and NFC is definitely fun?, and they are everywhere! For a research project I’m exploring different RFID tags and solutions. I several types around for a long time, but never found the time to actually work on it, so last nightI thought I give it a try, and I […]
Contactless payment ring – A tutorial on NFC antenna coil design
Jatinder writes, ” I have a done a video about a contactless payment (NFC) ring that I have made. The video talks about NFC antenna coil design and how I used the concepts to make the wearable ring.” Via the contact form.
An NFC implant to open doors and unlocking PCs
Fred over at the 430h forum shared another project using his NFC implant and an MSP4305529 to unlock his PC: I recent completed the prototype of my LoginNFC project. It’s a combination of MSP430 acting as a USB keyboard (and CDC serial for configuration) and a TRF7970A NFC reader. The prototype was done with a […]
TI Design Contest: Envision the ultimate NFC wearable
TI has announced a contest for NFC based wearable designs. Do you dream of creating a solution to make monitoring health and fitness activities easier? Using near field communication (NFC) in your designs can help! We want to hear your ideas for the next wearable design based on our RF430FRL15xH NFC sensor transponder in our […]
Using a standard coil for NFC tag implant reading
Limpkin writes: Who knew it’d be possible to use this coil to read NFC tags? A while ago I backed the xNT campaign , which aimed at making an NTAG216 based NFC implant for different purposes. After a few months of waiting and a few weeks of trying to find someone in Switzerland willing to […]
Video: Maker Faire NY 2013: Arduino NFC
In this video from the 2013 Maker Faire New York, Don Coleman takes the stage in New York to discuss Near Field Communication (NFC) using the Adafruit and Seeed Studio NFC shields on an Arduino. Coleman is a software developer and is co-authoring a book on NFC, PhoneGap and Arduino for O’Reilly. Via Make.
DEFCON 20 – NFC Hacking: The Easy Way
Eddie Lee, a security researcher at Blackwing Intelligence, gave this presentation at last Summer’s DEFCON 20 conference. His technique involves using NFCProxy, an open source software tool released at the conference to analyze 13.56 MHz RFID protocols and proxy transactions using Android phones. NFCProxy can view the wireless transmissions from the perspective of the tag […]
Samsung’s NFC Tec Tiles
Samsung has debuted Tec Tiles. These NFC smart stickers (shown above at actual size) are designed to be preprogrammed with information of your choice and left to be read by other NFC equipped phones. In order to program a tag, you’ll need to have the Samsung Tec Tile app on your NFC equipped phone, then […]
