Lenstag is a new software system for iOS, Android and even for your desktop ([
]) that allows photographers to record the serial numbers of their equipment. If the equipment is ever 'borrowed' without your permission you can flag the numbers with Lenstag and a growing list of companies will check with them before purchasing anything. You can also check the list yourself before following up on that craigslist sale item. More information here:
