Claim 12:
13. The identifying system of claim 1, wherein the identifying system is configured to identify at least two passive medical identification devices, wherein the at least two passive medical identification devices are differing in identification of features comprising: resonant frequency, effective magnetic dipole moment, maximum oscillation angle, zero excitation amplitude frequency, oscillation damping, resonant frequency of a further oscillating element of the passive medical identification device, amount of change of the resonant frequency depending on an excitation amplitude of an exciting magnetic field, velocity of change of the resonant frequency depending on the excitation amplitude of the exciting magnetic field, sensitivity of the respective resonant frequency to an external magnetic field, generation of harmonics of the induction signals.
