How does it work? |
The proximity technology reader constantly transmits a low-level fixed RF signal that energizes the card. When the card is held at a certain distance from the reader, the RF signal is absorbed by a small coil inside the card and powers up the card's microchip, which contains a unique identification code. Once powered, the card transmits the code to the reader. The whole process is completed in microseconds. |
