5 Determining installation position for an ex-
ternal reader
The type of identification media used determines the external reader
installation position.
Active ID media (transponders) have a wider read range than passive ID
media (cards).
5.1 Use of transponders
The transponder-to-reader range (read range) extends up to 60 cm.
Readers are able to communicate through materials such as wood,
steel and concrete when used with active transponders. The reader can
be mounted either on the inside or on the outer side.
