Contactless key fobs

Contactless key fob

— a compact electronic identifier for opening a door, turnstile, or other access point when held up to a reader. The key fob format is convenient to carry with your keys, making it suitable for personal access without using a plastic card. Compatibility depends on the frequency and standard of the RFID tag, not just on the device’s appearance. Before purchasing, check support for the specific system and whether a new identifier can be added to its memory.
