Product Description
Read/write tag 13.56 MHz (inductive)
Read/write tags in this frequency range save larger quantities of data and offer a considerably
higher reading speed than read/write tags of the 125 kHz system. IQH-* and IQH1-* read/write
heads from Fuchs are compatible with most existing read/write tags that comply with
standard ISO 15693. With the IQH2-* read/write heads you can use read/write tags that comply
with standard ISO 14443A.
The 13.56 MHz technology even allows smart labels (read/write tags in the form of adhesive
labels with printed barcode). Currently available read/write tags have a memory capacity of
64 bits of read only code and a maximum 2 KB of programmable memory.
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).
