The Guardscan Patrol Tour System features the latest in memory chip technology in the extremely durable GS3000 scanner. It is the ideal solution for companies wishing to track employees whose work duties require moving from place to place. Each IButton has a unique digital serial number and is assigned a name (North laundry door for example), we place these digital checkpoints throughout your property and our officers MUST scan these checkpoints each visit to your property. This system is not only used for verification of our officers stops on your property but as a digital timecard for the officers themselves. In short, if they don’t scan the checkpoints they will not be paid for the time. This way there is no question of who was where and when. This system has proven especially useful in court with our client for an eviction, When we provide the officer, the report and the Guardscan printout it is very difficult to dispute our efforts and findings.
