NFC is a ruby wrapper for the Near Field Communication library. The Near Field Communication library works with many USB RFID readers, so this gem lets you read RFID tags.
Only supports ISO1443A (MIFARE) tags right now.
require 'nfc' # Read your tag and print the info. p NFC.instance.find # NFC#find will return immidiately, which means you should have a tag # sitting on the reader when running it. If you'd like it to block until # it detects a tag, give find a block like so: NFC.instance.find do |tag| p tag end # You can even run in an infinite loop if you'd like to continually find # tags: loop do NFC.instance.find do |tag| p tag end end
A USB RFID reader. I'm using the touchatag.
$ sudo port install libnfc
The install the gem:
$ sudo gem install nfc
NOTE!!!! The nfc gem requires libnfc version 1.2.0 or greater!
