125 KHz radio frequency proximity card

It allows the automatic identification of the user by radio frequency, RFID. Passive card contains a chip that, when approached to the reader, receives an induced current that activates it. When activated it returns an identification code to the system, therefore it does not require any battery.
It communicates with the reader through a low frequency radio antenna at 125 KHz.
Made of PVC, it has a format similar to bank cards so it is easy to carry in any card holder compartment.
