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' # Create a new context ctx = NFC::Context.new # Open the first available USB device dev = ctx.open nil # Block until a tag is available, then print tag info p dev.select # You can even run in an infinite loop if you'd like to continually find # tags: loop do p dev.select end
A USB RFID reader. I'm using the touchatag.
First install libnfc. I installed libnfc via homebrew:
$ brew install libnfc
The install the gem:
$ sudo gem install nfc
NOTE!!!! The nfc gem requires libnfc version 1.7.0 or greater!
