Secure ID eTrak
|The Secure ID eTrak system is an electronic
labelling system that uses radio frequency to identify and count closely spaced items
without the need to separate or scan individual tags. It offers advantages over optical
barcode systems and other Automatic Data Collection technologies. It can be used in a
variety of applications, where it is desirable to remove dependance on Line Of Sight,
Physical Contact and Operator Intervention.
The Secure ID eTrak RF/ID technology is fast; up to 50 assorted or identically coded items can be scanned, identified and counted in one second, at a range of up to 4 meters from the Secure ID eTrak reader.
A unique "anti-clash" protocol incorporated into the technology eliminates the contention problem which normally occurs when conventional radio tags respond simultaneously to an identification command. This anti-clash protocol allows for tags to be simple in design and very low in cost.
The Secure ID eTrak system consists of a transponder or "tag", and an interrogator or "reader". The tag can be a single, integrated circuit chip bonded to a flat, printed antenna. Tags are completely passive and do not require batteries to operate. They are therefore both environmentally friendly and long lasting. The tags can be attached to the inside of existing packaging or labelling and encoded with a user defined or precoded numbering system. When scanned, the tag can provide item information similar to barcode systems.
A wide range of encoded information and chip configurations can be
designed to suit specific applications. Tags are read collectively without the need to
separate or position the tags individually over the interrogator. Due to the absence of
tuned cicuits, the antenna can operate in a wide range of illuminating frequencies.
After the tag data has been read, the tag clock receives the "power break" signal. The tag, thus signalled that its data has been read, mutes itself for a pre-determined length of time. The muting or "sleep" process is repeated for each tag, until all the tags in the operating volume have been identified or counted. The "sleep" process is the basis of the anti-clash feature which allows batch identification and counting of multiple tags that are all broadcasting their contents within the same interrogated volume.
