Device for controlling selective access to at least two compartments inside an enclosure

摘要

Apparatus for controlling access to at least first and second compartments defined inside an enclosure of a dispenser for goods and/or services, in such a manner as to prevent access to the second compartment while allowing access to the first compartment. An identifying object of the access-seeking person is recognized, the object being inserted from outside the dispenser. The resulting signal is communicated in an encrypted manner with a central unit which, in turn, communicates in an encrypted manner with an actuator, so as to control the actuator. The actuator is disposed inside the second compartment and is adapted to allow opening/closing of a lock associated with the second compartment. The central unit generates an encrypted message with the aid of an own key specific to the central unit. The actuator is also adapted to decrypt the message in order to recover such own key, the latter thus becoming the derived key adapted to be used to generate at least one communication message between the actuator and the central unit, and vice versa.
