Green RFID-TAG-BLACK reference proximity keyring, without labels. Radiofrequency identification device compatible with RFID/EM readers at 125 Khz.
This key fob is a passive device that requires no batteries or maintenance and is activated by touching it to a compatible reader, without the need for physical contact.
It contains a chip that, when approaching the reader, receives an induced current that activates it. When activated, it returns an identification code to the system, so it does not need any battery.
