The device can work with maximum 223 keys. The key is a metal tablet with diameter of 17 mm and 3 or 5 mm high (depending on the key type: F-3 or F-5). The tablet contains a specialised Integrated Circuit. Each key has it's own unique code assigned. The number of possible combinations is 10 to the power 14.
The device is enclosed in a plastic case and could be placed dozens of meters from the key reader. Its reader is equipped with a LED indicator, which shows the state of the device.
The programmed data of keys and the configuration mode of the device are stored in the EEPROM, so no changes, or even a complete lack of power supply affect the stored data.
Each device comes with four iButton keys
