Abstract
A sensor element is for testing a flat data carrier having a spin resonance feature. The sensor element includes a magnetic core having an air gap, which is delimited by two pole surfaces of the magnetic core and into which the flat data carrier can be inserted in order to be tested, a polarization device for generating a static magnetic flux in the air gap, and a resonator device for exciting the spin resonance feature of the data carrier to be tested in the air gap. The resonator device has a signal source and a plurality of stripline resonators which are simultaneously fed from the signal source, and the stripline resonators are formed in a planar manner with a main extension plane which is plan-parallel to at least one of the pole surfaces of the magnetic core.
