Abstract
A sensor element for testing a flat-surface data carrier having a spin resonance feature. The sensor element includes a magnetic core with an air gap, into which the flat-surface data carrier can be inserted for testing, a polarization device for generating a static magnetic flux in the air gap, a resonator device for exciting the spin resonance feature of the data carrier to be tested in the air gap, having at least one stripline resonator fed by a signal source, and a modulation device for generating a time-varying magnetic modulation field in the air gap parallel to the static magnetic field. The modulation device has a plurality of modulation coils, which are designed and configured for generating different modulation frequencies so that the modulated magnetic field generated by the modulation device, together with the polarization device, has different modulation frequencies at different locations within the air gap.
