Main idea is to develop simple API to reader, and than provide useful abstractions on top of it to quickly write applications to respond on tags which come in range of RFID reader using RFID::Biblio::Reader.
Writing support for new RFID readers should be easy.
RFID::Biblio::Reader::API provides documentation on writing support for different readers.
Currently, two serial RFID readers are implemented: 3M 810 and CPR-M02 which have USB-serial adapters.
There is also simple read-only reader using shell commands in RFID::Biblio::Reader::librfid.
