3 Functions and features
In connection with the evaluation unit DTE10x the read/write head ANT420/
ANT421 enables non-contact reading and/or writing of the RFID transponders
(ID tags) conforming to the system�

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�
