Patent ID: 8581706

Claim:
A method for contactless communication of a reading device with at least two communication-ready applications located on a portable data carrier, comprising the steps: generating a first communication-readiness signal to the reading device for a first of the at least two applications, the communication-readiness signal comprising a first identification number which is assigned to the first of the at least two applications and indicates to the reading device the communication readiness of said first application, and generating a second communication-readiness signal to the reading device for a second of the at least two applications, the second communication-readiness signal comprising a second identification number different from the first identification number, which is assigned to said second application and indicates to the reading device the communication readiness of said second application, and storing information in a nonvolatile memory of the data carrier about which of the at least two applications was last selected for further communication by the reading device, wherein the reading device selects for further communication one or more of the at least two applications via the identification numbers assigned to the applications.
