Abstract: There is described an RFID tag IC, comprising: i) an NFC interface configured to initiate a power-up, when coupled with an HF field, and receive a read command from an RFID device; ii) a non-volatile memory, wherein the non-volatile memory is configured to store a counter value; and iii) a processing unit configured to increment the counter value when coupled with the HF field, set an increment flag, when the increment is successful, and thereby block a further increment of the counter value, in particular when fulfilling the read command, and reset the increment flag after fulfilling the read command. Further, a communication system and a method of operating are described.

Abstract: An object is disclosed, the object (100) comprising a body comprising an antenna; and an integrated circuit embedded in the body and electrically connected to the antenna for receiving and transmitting wireless signals. The integrated circuit receives wireless signals at first and second different frequencies, waits until a command is received at the first frequency from a first reader device before transmitting a first signal and, upon detection of a signal at a second frequency different to the first frequency from a second reader device (201), transmits a second signal without waiting until a command is received.

Abstract: A Radio Frequency Identification (RFID) tag is disclosed. The RFID tag includes an antenna to receive an input AC signal and a tuning system coupled with the antenna to optimize signal strength of the input AC signal. The tuning system includes a charge pump rectifier. A diode rectifier is included and is coupled with the antenna to receive the input AC signal after the tuning system optimizes the signal strength by tuning input impedance of the antenna.

Abstract: An electronic counter is provided having a sequence of memory cells and increment logic. Each memory cell of the sequence is non-volatile and supports a one state and a zero state. The one state can also be referred to as a ‘programmed state’, the zero state as an ‘erased state’. The counter is configured to represent at least part of a current counting-state of the counter as a pattern of one and zero states in the memory cells of the sequence of memory cells, and increment logic configured to advance the pattern of one and zero states to a next pattern to represent an increment of the counter.
