Reader Technology
Patented Cotag® Reading Technology
Real Hands-Free is based upon Active Tag Technology where an onboard long-life lithium battery enhances
the output signal from the tag to the reader. The key advantage using Active Technology is the significant
increase in range from which the tag can be successfully interrogated by the reader, this being typically
between two to three times greater compared to that of common place passive cards.
Active cards and tags use low frequency magnetic signals, which have the key advantage of being able to read
through non-magnetic materials with little or no reduction in range. This allows tags to be interrogated
without the need to remove them from pockets or handbags thus giving the user unparallel freedom and
convenience without compromising site security. Active technology can overcome problems associated with
vandalism simply by mounting the Reader within walls or mounted ‘safe-side’ within glass-fronted
lobby/reception areas.
There are two types of Reader available which fully embrace the
true user benefits of real Hands-Free for access control
applications. The unobtrusive wall-mounted HF500-Entro Hands-
Free Reader is designed for quick and easy installation and the
BC-5270 Loop Technology Reader which provides even greater
reading range and also allows for its antenna to be suitably hidden
within the door frames or walls thus providing the customer a
clean, minimalist, aesthetic pleasing solution.
Passive Proximity Technology is based upon the same principles
as active Real Hands-Free, but without the onboard battery, this
results in a significantly shorter reading range as it’s output power
is derived solely from the magnetic fields generated by the
Reader. Passive Technology offers a cost effective access solution
for many systems except those requiring Loop Technology
Readers.
All Bewator’s Cotag® Active and Passive Technology cards and
tags can be mixed together on any Bewator system, allowing the
customer to issue the most suitable technology card or tag to that
user depending upon their requirements. This is particularly
useful for facilitating disabled staff requirements and also for clean
room operations where garments typically only have pockets on the inside.
Mifare® Contactless Smart Card Readers
With an increasing demand for a multi-application card solution, Bewator is
teamed together with the world’s largest Smart Card Technology company
Gemplus® to bring reliable and robust Mifare® Smart Card Readers for use
in access control systems. These Readers utilise the unique chip serial
number found in every Mifare® Smart Card and uses that number as the
individual’s identifier within the access system.
Automatic Vehicle Identification (AVI)
RFID tagging of vehicles creates particular technical challenges due to the
high levels of electrical background noise caused by the ignition system and
physical vibration/stone impacts associated with normal road going
conditions. Bewator’s Cotag® Active Technology AVI addresses these and provides a real world solution for
use in car parking and fleet management applications, giving fast and reliable reading of tags fitted to the
underside of vehicles. The IB-970 Vehicle tag is specifically designed to withstand harsh environments, being
not only certified for use with the Ministry of Defence military vehicles but also passing strict EMC approvals as
required by the Home Office’s VIDG Specification 5 for use by the Police & Fire Services.
