RFID readers and RFID tags exchanging encrypted password
First Claim
Patent Images
1. A radio frequency identification (RFID) reader, comprising:
- an antenna arranged to transmit a transmission wave; and
circuitry arranged to modulate on the transmission wave symbols encoding a tag command and a callout associated with the command, the callout containing data and at least one portion of a preset password, the data and the at least one password portion having been encrypted using a preset kernel.

Abstract
RFID system components, such as readers and tags, communicate where at least a portion of data or a password is transmitted in encrypted form. The reader transmits a command, along with data or a password encrypted using an encryption kernel. In some instances, the tag itself has sent the kernel.
