Abstract: The invention relates to a method for saving power especially for tag talks first data transmission in radio frequency identification (RFID) systems including a tag containing a non-volatile memory, a digital block and an analogue block and a static random access, wherein the data of the non-volatile memory are prefetched from the non-volatile memory into the digital block and the tag talks first data will be stored in the static random access memory embedded in the digital block.

Abstract: Embodiments of an electronic device are disclosed. In one embodiment, the electronic device includes a circuit board, a central processing unit (CPU), an RFID IC, and a physically secure communications channel. The circuit board includes a radio frequency (RF) antenna, the CPU is connected to the circuit board and includes a CPU-to-RF identification (RFID) interface that does not support a digital security measure which requires asymmetric key cryptography, the CPU being enclosed within a package. The RFID IC is connected to the RF antenna and has an RFID-to-CPU interface that does not support a digital security measure which requires asymmetric key cryptography. The RFID IC also has non-volatile memory that stores configuration data for configuring the electronic device. The physically secure communications channel connects the CPU-to-RFID interface to the RFID-to-CPU interface and the physically secure communication channel is protected from physical access by a structural barrier.
