nfc version 2.0.0 has been released!
* <http://seattlerb.rubyforge.org>
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.
Changes:
### 2.0.0 / 2009-08-07
* 2 major enhancements
* Switched from FFI to a C backend
* Now depends on libnfc 1.2.x
## FEATURES/PROBLEMS:
* Only supports ISO1443A (MIFARE) tags right now.
## SYNOPSIS:
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
## REQUIREMENTS:
* A USB RFID reader. I'm using the touchatag[http://touchatag.com].
* libnfc
## INSTALL:
First install libnfc[http://libnfc.org/]
I installed libnfc like this:
$ ./configure --prefix=/usr/local
$ make && make install
The install the gem:
$ sudo gem install nfc
NOTE!!!! The nfc gem requires libnfc version 1.2.0 or greater!
