In a small or mid-size company, the asset register is often a spreadsheet that drifts away from what is actually in the building. Laptops are swapped in a hurry, monitors move between desks, and when someone leaves, nobody is sure which devices they had.
Asset tags with barcodes are cheap, and most companies already have them on their devices. The missing piece is a quick way to read them where the devices are, in offices, meeting rooms and storage cupboards, and get the result back into the register without typing serial numbers.
