A secure epass - no. based on a doubly chip - technology

摘要

A manipulation - visible credential (100, 200) has, on a funkfrequenzdentifikations - housing (rfid) with an antenna (232) and a subordinate antenna (234), the radio frequency - identification - housing defining a first part (122, 222) of the authorization check (100, 200). The credential (100, 200) has on an rfid - housing defining a second portion (214) of the authorization check (100, 200). The subordinate rfid - housing selectively connected in such a way with the first antenna (234), that an interrogation signal (250), based on the first antenna (232), is transmitted to the first rfid - housing via the subordinate antenna (234).
