Direct contactless communication between transponders
First Claim
1. A method for the communication of microelectronically integrated data carriers which contain contactless communications devices, characterized in that at least two of the data carriers are brought into the reciprocal range of their contactless communications devices;
- at least one component generates an alternating electromagnetic field so that the data carriers are supplied with sufficient energy for the internal processing and communications operations; and
data can be transmitted directly from at least one of the data carriers to at least one other data carrier.

Abstract
In a method and a device for the communication of microelectronically integrated data carriers, which contain contactless communications devices, at least two data carriers are brought into the reciprocal range of their contactless communications devices, at least one component (field generator) generates an alternating electromagnetic field, by means of which the data carriers are supplied with sufficient energy for the internal processing and communications operations, and data can be transmitted directly from at least one of the data carriers to at least one other data carrier.

21. A device for the communication of microelectronically integrated data carriers, which have contactless communications devices, characterized in that:
-
at least two of the data carriers having contactless communications devices are in a reciprocal communications range;
at least one component is available for the generation of an alternating electromagnetic field, which supplies the data carriers with energy for processing and communications operations; and
this field spans a sufficient spatial area of adequate field strength, in which the data carriers can be supplied for the direct communication. - View Dependent Claims (22, 23, 24, 26, 27, 28, 29)
