4.3 Operating principle
The readers are used for contactless data exchange with tags. For this the controller sends com-
mands and data via the interface to the reader and receives the corresponding response data
from the reader. The reading of the IDs of all RFID tags in the read area or the writing of an RFID
tag with a specific production date are examples of typical commands. To communicate with
the tag, the data of the reader is coded and transferred via an electromagnetic field, which at
the same time supplies the tags with power.
A reader contains a transmitter and a receiver, an interface to the interface module and a coup-
ling element (coil and dipole antenna) for communicating with the tag. Electromagnetic wave
propagation is used for the transmission between reader and tag on devices for the UHF range.

Fig. 3: Operating principle of UHF-RFID
The antenna of the reader generates electromagnetic waves. This produces a transmission win-
dow as a so-called air interface in which the data exchange with the tag takes place. The size of
the transmission window depends on the combination of readers and tags, as well as on the
relevant environmental conditions.
Each reader can communicate with a number of tags. This requires the reader and the tag to
operate in the same frequency range. Depending on the power and frequency used, the device
ranges vary from a few millimeters up to several meters. The specified maximum read/write dis-
tances only represent typical values under laboratory conditions without allowing for the effect
of materials. The achievable distances may vary due to component tolerances, the mounting
situation in the application, ambient conditions and the effect of materials (particularly metal
and liquids).
