Description

The AT88RF256 is an RFID (radio frequency identification) chip designed to work on

the industry-standard carrier frequency of 125 kHz. Applications include access

control, asset identification, industrial tagging, animal identification and other

applications where modest security capabilities are necessary. Security features

include locking of sensitive information to prevent tampering, optional passwords to

prevent unauthorized access and unique serial numbers locked into the chip by Atmel.
