JWM intelligent passive electronic lock is composed of three parts: stainless steel padlock, intelligent key, and management software. First of all, stainless steel padlock can be completely waterproof to eliminate the problem of rust. Each lock has a unique ID number that cannot be copied, corresponding to the matching information set in the software. Where is it installed? When will it be installed? What’s the corresponding number? Itinerant inspectors can open all the locks they want with only one key, and they can set the key, take out time, return time, and work time by software to have access to the lock. The management software will automatically record the lock opening time, lock locking time, and the corresponding personnel. Such a system completely solves the lock control problem that we have struggled to manage for many years.
