What Is Inside a Keycard? Understanding Microchips and RFID Technology

Explore the components of keycards, including microchips and RFID technology, and how they communicate for secure access.

112 views

Keycards contain a microchip and an RFID (Radio Frequency Identification) antenna. The microchip stores data that identifies the card to a corresponding reader system, while the RFID antenna allows the card to communicate this data wirelessly. When a keycard is placed near a reader, the reader sends a signal to the card, prompting the microchip to respond with its stored information, granting access if the data matches the system's requirements.

FAQs & Answers

  1. How do keycards work? Keycards use a microchip and RFID antenna to communicate wirelessly with a reader, granting access based on stored data.
  2. What is RFID technology? RFID stands for Radio Frequency Identification, a technology that uses radio waves to identify and track objects.
  3. Are keycards secure? Yes, keycards offer a secure way to control access, but security depends on how the data is managed and protected.
  4. Can keycards be cloned? Yes, if not properly secured, keycards can be cloned, which is why it's essential to use encryption and security measures.
