4 Functions
4.1 Operating principle
The ID tags are operated passively, i.e. without battery. The energy required for
operation is supplied by the read/write head.The physical principle of the energy
transfer is based on inductive coupling. The integrated antenna coil in the read/
write head generates a magnetic field which partly penetrates the antenna coil of
the ID tag. A voltage is generated by induction that supplies the data carrier with
energy.
