7.3 Range and detection
The range between transponder and the Kemro UserID module is de-
pendent on the installation situation, the antenna size (with OEM versions)
and the transponder used. The range increases if the antenna (for OEM
versions) or the stand-alone module are installed in non-metallic materials.
In addition, the range increases if a sufficiently large surface is available for
the transponder antenna. Thus, check card transponders have a slightly
higher range than transponders in the form of key chains.
The simultaneous detection of up to four transponders is possible. If multi-
ple transponders are in the reception area of a Kemro UserID module
simultaneously, the module will automatically attempt to read out the trans-
ponders, filter out unreadable transponders and make the valid card(s)
available at the interface of the device driver.
