A wireless RFID reader for charging authorization with Bluetooth, operating at a frequency of 13.56 MHz and supporting MIFARE® Classic and MIFARE® DESFire technologies. It is powered by two AAA batteries and can last up to approximately two years under normal use.
It has an accelerometer and low battery voltage sensor built into its body; two function buttons, a pair of LEDs and a buzzer make operation easier and, in combination with the accelerometer, can alert the user to the need to log in with a card.
