Both the company and the university can build, as part of its own needs, a system that will easily organize the way of issuing and retrieving keys and in an easy and transparent way will allow identification of the person in possession of the key. The program enables very extensive reporting for control purposes. Each key issuing point is equipped with a reader and a terminal (computer with monitor) on which the software is installed. The person issuing the keys has his own card / keyring. The employee retrieving the key brings his / her keychain / card closer to the reader, which verifies the possibility of the key being picked up by the person. After positive verification, a message appears on the monitor screen confirming the right to retrieve the key. Then the porter approaches his card / keyring to authorize the transaction and then issues the above-mentioned key. Thanks to this we know exactly who is at the moment the owner of the key and which rooms are occupied at the given time. In facilities where there are several key dispatch points (lodge), the person collecting the key at the porter’s lodge no. 1 can return it at the porter’s lodge No. 3, and the fact of the return will be visible at each key dispatching point.
