Each access key is programmed with the user’s ID and to which an exclusive 8-byte code is assigned. The user data is recorded in the system memory every time an access card or smart key interact with the module. Once unlocked, there's a close chamber (volumetric limiter) with a 30 to 35 litre capacity inside the intake bin or drum that restricts the amount of waste to be deposited. The waste goes down the container after the bin cover is closed. The purpose is for the user to manage the waste in a way that makes the most of the available space in that chamber. The system measures the discarding from that particular user by how many times the bin cover was opened. And there’s bins for organic and for recyclables.
