That's interesting. I work for a Telco company and we track inventory without stickers. I know we did; but not anymore. Instead we have a CMDB (change management / inventory database) which tracks all items related to the business (like a router, user, link, or vpn connection). For laptops, cellphones, etc. we track manufacturer serial numbers (which relates to support contracts). To avoid theft we use vendor tracking/remote disable/erase. I hope this helps.
