Read/Write
Modules
Flexible in application and robust, RFID
write/read systems provide for quick
and reliable identification of objects at
various distances.
Primarily developed for application in
production, commerce and logistics, the
user memory has up to 2kb, depending
on the type of transponder, which allows
for the recording of information relating
to the product to be stored without
having to be connected to an external
database.
Wherever the mobile storage of data is required,
e.g. for object identification, service or storage
management, the RFID module is the ideal
solution.
• Integration into already existing
systems is possible.
• relatively wide reading-range
• anti-collision, logging by more
than one transponder in the field
• software updates possible
Basics of RFID technology

distance
Radio Frequency IDentification (RFID)
comprises wireless data transfer on the
physical basis of electro-magnetic alter-
nating fields. A RFID system consists of a
transponder and a mobile or stationary
write/read unit with antenna.
Transponders feature a micro chip and a
coil/antenna in different casings (plastics,
glass, coins, key holders, smart label) and
work within different frequency ranges.
With regard to power supply transpon-
ders are distinguished as:
• active
(with battery for own power supply)
• passive
(power supply for data transfer
inductive from write/read unit)
