Max Microchip GPL is a multi-protocol RFID reader for scanning pets implanted with an under-skin ID microchip. The external hardware required can be built with no soldering, and connects simply to the PC's Line In Audio jack.
The objective of this project is to create an implementation of the EPCglobal reader protocol, for use by application developers, that will provide a uniform interface to today's major RFID reader platforms. See http://www.accada.org for more details.
