Abstract
In various embodiments, a transponder unit for the contactless transmission of modulated data to a reader is provided. The transponder unit may include: a clock generator configured to generate a clock signal and to synchronize the clock signal in a synchronization mode, on the basis of a signal received from the reader; and a modulator configured to take the clock signal from the clock generator as a basis for modulating data; wherein the modulator is configured to send a signal for starting the synchronization mode to the clock generator.
