Non-contact integrated circuit has RFID and UHF communications interfaces, data processing unit and a multiplexer for selecting the desired communications interface

摘要

Non-contact integrated circuit (IC) comprises an RFID communication interface (1) with an antenna coil (L) for receipt of a first induced alternating voltage signal (Va), a processor unit (DPU) and a second UHF communications interface (2) with a UHF antenna for receipt of a second induced alternating voltage signal (Vb). Multiplexing means are also provided for connecting the data processing unit to either of the communication interfaces.
