2. General description of trovan
access guard.
This chapter gives a brief explanation of all different components of the
trovan
access guard system.
2.1 Identification labels
All
trovan
identification labels or transponders are guaranteed to be world-wide unique. This means that every
identification number will be produced only once regardless to the type of transponder. The reading distance of
each transponder depends on its size and shape. Reading distances up to 120cm (47 inch) can be achieved
when the right combination between transponder and reader is used.
2.2 Readers
The basic components of the entire system are the access control readers. Every reader consists of an antenna
and a decoder.
2.2.1 Antenna
When a transponder is held within the reading distance of the antenna, the transponder signals will be received
by the antenna and are passed through to the decoder. Because the entire system is based on inductivity
the antenna may not be placed upon or near to any metal. This will decrease readingdistance and can
even destroy the antenna.
2.2.2 Decoder
The decoder is the intelligent part of the reader. It calculates the actual identification code of the transponders
and can perform different actions with these codes depending on the location of the decoder, date and time etc.
