125 kHz rfid
A 125 kHz tag contains a low-frequency RFID chip. Due to the low frequency, these chips have a relatively short range. The chips can communicate with other devices at a distance of 2 centimeters to 100 centimeters. This makes these tags ideal for access control systems and lockers, for example. A 125 kHz tag has a memory capacity ranging from 64 bits to 1 kB. The capacity determines how much code you can program onto the tags. Are you looking for RFID tags with a frequency of 125 kHz? Then NFC World offers you a wide selection of tags to choose from.
