This patented technology offers many benefits to system designers, integrators and end users. Not least of these is that the tags do not interfere with other electronic surveillance systems causing false alarms etc. The typical error rate is 1: 1 million in worst case noise, this is significantly better than any other tag systems. 
Reading range is determined by the size of the reader aerial and by the power source used. The tags can be covered by clothing, leather, glass etc. without affecting their performance. 

2192 Mullion Reader
The mullion reader has been designed to complement the loop configuration
systems providing a low cost alternative, which is simple and quick to install.
LED indication is provided to indicate power to the reader and that a tag is
being read. A separate Green LED can be controlled externally to indicate
acceptance of the tag by the access control system.

The progeny hands free reader can simultaneously interrogate tags up to 1.2 metres from the reader housing. This range can be increased using external aerial loops to over 3.0 metres. Using an external aerial measuring 2 x 2 metres range increases to 3.0 metres plus, assuming a noise free environment. The RF communications between each tag and reader is scrambled to eliminate the chance of simulated tokens being used. Reading range is determined by the size of the reader aerial and by the size and power source used in the 

2191 Active RFID Reader with Direction Sense
This reader is physically similar to the 2190 but with extra electronics for direction sensing. This reader has two interface outputs. One output represents a tag moving in and the other represents a tag moving out. This is an ideal partner to the new specification P1 controllers with its two reader inputs.
