How the System Works
Each Smart Card reader transmits a 125 KHz frequency field (the
electromagnetic field), which is picked up by an aerial in the Smart
Card. The reader has two read bands within this field; an inner and
outer band, and these are controlled and rapidly oscillated by the
readers on-board microprocessor.
The Smart Card microchip, is a passive device which holds a unique
factory encoded ID number that cannot be duplicated, making it very
secure indeed. As a card enters the reader's electromagnetic field, it
is automatically activated by the field's energy.
Smart Card Integrity
With up to 34 billion different combinations of ID number, there is no
chance of duplication. In addition, each ID number has built-in security
and integrity checks ensuring that it cannot be misread.
A cross-reference list correlating the external printed card number and
the programmed ID number is also provided, for easy system
administration.
In addition, Tensor can also provide smart card software, which gives
you an easy way to professionally produce your own ID cards
Benefits
- Tensor Smart Cards have no on-board battery that can fail.
Theoretically, this means that each card has an infinite life, and can
be read an infinite number of times.
- The same card can be used for both Time and Attendance recording and
access control throughout your site
- Factory encoded ID code cannot be duplicate, therefore very secure
- Adhesive labels for photo and company logo
- Size of a standard credit card (thin and flexible enough to be carried in your wallet)
