摘要： A customer medium (1) for detecting the utilization of services is proposed, comprising a first and a second antenna (2, 3) for long-range data communication, a third antenna (4), an integrated circuit (6) comprising at least one crypto-engine, one microprocessor (5) connected with the integrated circuit (6) or integrated into the integrated circuit (6), an operational amplifier (8) and an RF transceiver (7) connected to the second antenna (3), where the third antenna (4) is connected to an NFC-module in the integrated circuit (6) and is used for the short-range data communication in an active mode of the customer medium (1), where the first antenna (2) is used as a wake-up antenna for receiving an amplitude-modulated wake-up signal if the customer medium is in a “sleep” mode, where the signal received by the wake-up antenna (2) is demodulated and amplified by the operational amplifier (8) serving as the wake-up detection module and is evaluated by the microprocessor (5) partially activated in the “sleep” mode, where the microprocessor (5) is completely activated in the event of a valid wake-up signal, by which the customer medium (1) enters the active mode and where the operational amplifier (8) is the only component of the customer medium (1) that is fully active in “sleep”-mode.
