Method for selecting one or several transponders
First Claim
1. A method for selecting at least one transponder or sensor in RFID or remote sensor systems having a plurality of transponders or sensors with at least one reading device, the method comprising:
- determiningly preselecting individual transponders or sensors by at least one reading device; and
transmitting data for confirming, after preliminary selection of at least one transponder or sensor has taken place, asynchronously from the transponder or sensor to the reading device during at least one protocol segment.

Abstract
A method for selecting at least one transponder or a sensor in RFID or remote-sensor systems provided with a plurality of transponders or sensors (tags), in particular in systems provided with a plurality of reading devices, is disclosed. The inventive method includes the feature that in pre-selecting individual transponders or sensors by at least one reading device and, after the successful selection of at least one transponder or sensor, data, in particular for conforming the preselection, is asynchronously transmitted during at least one protocol section from the transponder or sensor to the reading device. The invention makes it possible to efficiently reduce the potentially disturbing control signals of the reading device(s), thereby improving the transmission characteristics of said systems.
