This is a bicycle registration system, running at http://www.bikexyz.com.
The fundamental premise of this registry is that every bicycle deserves its own URL. That URL then can be marked upon the bike in many, various places. The purpose being to make it trivial for anybody with a web browser to check the registration status of the bicycle. Also, having the freedom to mark the bicycle how ever and where ever (rather than with a single "tamper resistant" sticker) makes it more likely that the registration mark will survive obfuscation by bike thieves.
