Asset tracking

Hi Guys,

We are a team which provide IT support to a large warehouse. One of the devices we support are barcode scanners and Operations are losing them at a rate of 1 per day. As these scanners are costly to replace we are asked to find a solution to stop the scanners leaving the warehouse. We see that on our system the lost scanners are last seen near dock doors which brings us to the conclusion that workers are leaving the scanners on pallets when loading on truck trailers which are leaving docks.

Our idea is to have some RFID stickers on the scanners and have some sensor in front of Dock doors which would light up in realtime to let us know that the scanner has passed through them. It will should give us the details of the scanner and time when it was passed through the sensor

Is there already some system that can be implemented that we can utilise or give us ideas how to develop one ?
