Patent ID: 8643469

Claim:
A system for controlling access to an object with a door, the system comprising: a mechatronic locking device for blocking or releasing the door, wherein the locking device comprises a receiver, which is equipped to receive and evaluate a capacitive-resistive signal emitted by a transmitter and transmitted via the body of a user, wherein the locking device releases the door or not depending on a result of this evaluation, wherein the locking device comprises an outer receiver electrode and an inner receiver electrode not electrically connected in parallel to the outer receiver electrode, wherein the outer receiver electrode, if the door is closed, is accessible from outside the object and the inner receiver electrode from within the object, and wherein the locking device is programmed to assume a first unlocking condition when a matching capacitive-resistive signal is received by the outer electrode, and to assume a second unlocking condition when a matching capacitive-resistive signal is received via the inner electrode, and wherein the first unlocking condition is different from the second unlocking condition.
