3  Functions and features

In connection with the evaluation unit DTE10x the read/write head ANT410/

ANT411 enables non-contact reading and/or writing of the RFID transponders (ID 

tags) conforming to the system�

unit�

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�
