METHOD AND DEVICE FOR THE CONTACT-FREE TRANSMISSION OF DATA FROM AND/OR TO A PLURALITY OF DATA OR INFORMATION CARRIERS, PREFERABLY IN THE FORM OF RFID TAGS

摘要

A method and device for contact-free transmission of data from and/or to a plurality of data or information carriers provide that, after the exchange of information between a read and/or write device and a data or information carrier, said carrier is switched to a standby impedance mode in order to reduce undesired interaction with data or information carriers adjoining the antenna field. This mode differs from an initial impedance mode and communication impedance modes during the emission of an information signal from the data or information carrier.
