Abstract

An ID token includes a sensor, a communication interface, and a first microcontroller. The ID token includes a protected second microcontroller having at least one microcontroller communication interface, which is arranged in a holder of the ID token, wherein the microcontroller communication interface provides a data input and a data output. The first microcontroller is configured as a proxy for switching between the sensing of the measurement data by the sensor and forwarding of the sensed measurement data from the sensor to the first application of the protected second microcontroller by the microcontroller communication interface thereof on the one hand and forwarding of notifications for establishing a connection between the second application and the reading device and/or forwarding of APDUs by the connection between the second application and the reading device on the other hand.
