IC (Integrated Circuit) technology is nothing new. Embedding Contact IC chips in cards
has been in practice in parts of Europe and Asia for many years. Designed as a
security feature, IC technology works like this: an electrical current runs through the
circuit and is verified by the IC card. If valid, the IC sends a signal back to the
reader. Although this is a relatively simple procedure, its applications are
numerous. Please note, card readers may be mounted or unattached. (see Figure below)
The next generation of IC cards are now available: Proximity cards.
Proximity cards work on the same principles as their predecessor; an electric
current powers the IC chip and the card sends back a signal to the reader. The
difference being that the proximity transmission is done from a distance. You no longer need to be in contact with the
reader. To open a locked door simply wave your card at the door and it will unlock
for you. No more fumbling for a card buried in your wallet, or jingling around a key
chain, just walk up to the door and it will open for you. The distance at which the
card and reader can communicate can be adjusted from a few millimeters to a few meters.
The smaller the distance the tighter the security.
