It seems like everyone in Toronto is using proximity cards to unlock doors today. Hold up the card to the reader and the door unlocks. In fact, I leave my proximity access fob in my pocket and stand close to the reader and the door unlocks. This trick works with a purse too.
How does it work?
An HID card has a copper coil that works like an antenna. The reader puts out a radio signal that the card bounces back with a small distortion. That distortion is the number programmed on the card.
As you can see in the photo the coil is attached to two microchips. One for regular readers and a second for the new iclass cards. There is also a magnetic strip. This is three cards in one!
At Spadina Security we use Paradox Access Control systems with Prox cards for a variety of applications. The same system can work on the front door of a building and your single office door.
