1. A system of communication with an RFID transponder IC comprising:
- a primary host system emulating an over-the-air RFID interface;
a carrier incorporating two conductive contacts; and
an RFID transponder IC affixed to said conductive contacts;
wherein said RFID transponder IC is removably connectable to said primary host system through said conductive contacts on said carrier, and wherein when said RFID transponder IC is connected to said primary host system through said conductive contacts on said carrier, said RFID transponder IC communicates with said primary host system through said conductive contacts using an RFID protocol.

Abstract
This invention relates to a system of communicating with a radio frequency identification (RFID) transponder microchip (IC) for the purpose of accessing pre-programmed data. Such system involves direct electrical contact between the system reading the data from the memory in the transponder IC and the IC itself via two mechanical contact points. This system provides an interface with a transponder IC in order to energize the IC. Once the presence of the transponder IC is detected, the host system can read or write to and process preprogrammed data stored in the IC.
