Product Description
Data carrier 868 MHz (UHF)
Data carriers in this frequency range can be passive as well as active (with
battery) and use a specially-shaped rod antenna as the resonance element. The
passive transponders can be produced very cheaply and have a range of several
meters.
As material handling and the automotive sector requires ranges of 1 to 5 meters,
this system represents a low-cost alternative to microwave systems, particularly
because of its low transponder costs. The high carrier frequency supports large
data volumes and extremely short read times.

Handhelds
There are various handheld read/write devices available for controlling processes
(write/read functions, initialization of data carriers).
