Abstract
To minimise the power consumption when registering an electronic ticket, a bidirectional communication in a higher frequency band is initiated when the electronic ticket has received a wake-up signal in a lower frequency band via a highly sensitive receive module. During entry stamping, a wake-up telegram containing an identity of the detection space is transferred to and stored in the electronic ticket. The wake-up telegram is received in the lower frequency band by another receive module in the electronic ticket.
