I was browsing over at at the booq bag site today and discovered Terralinq. The folks over at booq describe Terralinq like this:

If you ever lose your booq® bag with its valuable cargo, Terralinq may help reunite you with your lost bag once it has been located and reported to Terralinq. To make this possible, each booq bag with Terralinq carries a unique item number on a metal label. Registering links a product’s unique number with an identity – yours. Should a registered bag be reported as lost & found, Terralinq will attempt to contact you with a bag’s location and the finder’s contact information.

This sounds like a pretty great system that; if you were to buy some other manufacturer’s bag you would have to pay for. In fact. see i-Trak. That’s what they do. Looking around the Terralinq by booq site it includes a login that lets the bag owner update and maintain their contact information over time. Props to the folks at booq for providing this service when you buy one of their bags!
