This revolutionary key management system makes the issue, collection and storage of keys much more efficient, reliable and more secure. The Key Captor module immediately detects the slightest change that has been made to a key or key ring. The issued or collected Key Cops are identified by embedded RFID tags. If a wrong key ring has been identified the system will detect it immediately and the user asked to intervene. Most importantly, it might turn out that the right key rings have been handed over but one of the keys has been substituted or broken off. Although this can be hard to determine visually, the system will automatically detect the slightest change that has been made to a key or key ring. The Key Captor can be used in combination or separately from the Key Conductor.
