METHOD AND DEVICE FOR THE POWER-SAVING OPERATION OF RFID DATA CARRIERS
First Claim
1. A method for power-saving operation of an RFID data carrier, whereby the RFID data carrier has a transmission/reception antenna, by way of which data are sent to and received from a transmission/read unit, respectively, by means of a radio signal within a transmission field, the method comprising:
- configuring the data carrier for a power-saving sleep mode, the data carrier responding to a wake-up signal to switch to a reception mode;
transmitting a wake-up signal to the data carrier, while at the same time;
transmitting a time datum to said data carrier, whereby the time datum shows the time that indicates how much time must still elapse until transmission of a command.

Abstract
A method and a device for power-saving operation of RFID data carriers, whereby the RFID data carrier has a transmission and reception antenna, by way of which data are sent to or received from a transmission/read unit, by means of a radio signal, within a transmission field, whereby the data carrier is configured for a power-saving sleep mode, and switches over to the reception mode by means of a wake-up signal. With the transmission of the wake-up signal, at the same time, a time datum is transmitted to the data carrier, whereby the time datum shows the time that indicates how much time must still elapse until transmission of a command. The data carrier configured with the sleep mode switches over to a reception mode by means of a wake-up signal, whereby the wake-up signal additionally has a time datum that forms a countdown time, and switches the data carrier into the reception mode briefly, after this time has elapsed, thereby causing the data carrier to receive a command.
