A method includes controlling a shared location. Item identifiers are read from a set of items (pertaining to one or more operators sharing the shared location) reaching a gate of the shared location. A verification request message for the item identifiers is broadcast for receiving corresponding verification response messages from central computing systems of the operators. A passage of the items through the gate is controlled according to the verification response messages. A computer program and a computer program product for performing the method are also proposed. Moreover, a system for implementing the method is proposed.
