RFID lyklaborði

A key fob contains a short-range radio transmitter/radio frequency identification (RFID) chip and antenna. It uses radio frequencies to send a distinct coded signal to a receiver unit in the device. This receiver also contains an RFID tag, which is some form of stored information. RFID key fobs have the same functionality as RFID smart cards. However, RFID lyklaborðar, also referred to as smart keys or simply RFID key fobs, are much more compact, practical and robust. Thanks to these features and their intuitive handling, the smart keys are often used in the areas of access control and time recording. Further advantages of the RFID key fob are the extremely high durability and their robustness against external influences.
