Method and device for operating RFID data carriers while saving electricity

摘要

The method involves transmitting or receiving data to or from a transmit-reader (1) by transceiver antennas (2, 5) of a radio frequency identification-data carrier (4) using a radio signal within transmitting fields (3, 6). Time information is transmitted to the data carrier simultaneously with transmission of a wake signal, where the time information exhibits time indicating elapsing time for transmission of instructions. The wake signal is transmitted to the data carrier by the transmit-reader at rest mode. An independent claim is also included for a device for operating a radio frequency identification (RFID)-data carrier.
