Abstract
A dual communication frequency RFID circuit (10) including: a first logic unit (13) for processing data signals received or transmitted by a first frequency by a first antenna (11), a second logic unit (14) for processing data signals received or transmitted by a second frequency by a 1 second antenna (12), a shared memory unit (15) connected to the first logic unit (13) and connected to the second logic unit (14) and including a shared password storage section (20) accessible by the first logic unit (13) and by the second logic unit (14).
Claims15
A dual communication frequency RFID circuit (10) comprising:
- a first logic unit (13) for processing data signals received or transmitted by a first frequency by a first antenna (11),
