What if a thief removes a serial number?
In the first place, the thief would not steal it. Thieves tend to avoid stealing items whose ownership is identifiable according to the police. However, if serial number is still removed, it indicates the item is stolen or illegitimate. Serial numbers may be visually removed or defaced, however, there is a way to retrieve serial number for many mobile devices. For most mobile devices, serial numbers are printed at the back of the unit and are also electronically stored in the device. For example for cell phones, the following key sequence will display the serial number of the device. *#06# RFIDs are about to be universally available. An RFID code can also be used instead of a serial number when an RFID chip is embedded in your equipment. For your option, we also provide tamper-proof labels. The tamper-proof labels are not practical to remove. Removal of the label will rip the case or significantly disfigure the case. As a result, it will make the item worthless to resell for a thief.
