Our RFT3xx-series is made up of ISO/IEC-15693 compatible write / reading transponders. Passive transponders (without support of a battery) generate their own working energy out ot the electromagnetic field and transfer the data back to the interrogator (write / reading unit).

The tag (transponder) which is in the frequency field of the interrogator has an UID (unique number worldwide), that allows to divide different transponders via the anti-collision-modus, even if several different tags are in the reading field at the same time. The UID is programmed by the manufacturer and is saved against overwriting.

In addition to that, the transponder has an additional data store, that can be read and programmed individually.
