1. A method of transmitting information between a radio frequency identification (RFID) tag and a server, said method comprising the steps of:
- encrypting, by said RFID tag according to a predetermined scheme, identification data identifying said RFID tag, to result in encrypted RFID information;
reading, by a RFID reader, said encrypted RFID information from said RFID tag;
transmitting, from said RFID reader to said server, a transmission, wherein said transmission includes said encrypted RFID information; and
decrypting, by said server according to said predetermined scheme, said encrypted RFID information to produce said identification data.

Abstract
An RFID system includes an RFID tag, an RFID reader, and a server. The RFID tag communicates to the server via encrypted information. The information may be encrypted with synchronized encryption keys. In this manner, the reader need not decrypt the information from the RFID tag. The effectiveness of malicious readers is thereby reduced, resulting in improved RFID tag security.
