How Do They Work?
Inside each 125kHz proximity card is a small antenna and a chip. When you bring the card close to a reader, magic happens:
- The reader sends out a signal
- The card’s antenna picks up this signal
- The signal powers up the chip
- The chip sends back a unique code
- If the code matches, you’re in!
This process happens in a fraction of a second, making it seem like the door opens instantly when you wave your card. The beauty of this system lies in its simplicity and reliability.
