Official Groundspeak Travel Bug Dog Tag:
A Geocaching Travel Bug® is a unique tracking tag that you can attach to items and give them goals for others to try and complete!
Each Geocaching Travel Bug® gets its own page on Geocaching.com where you can track its progress as it passes on from person to person or cache to cache.

Each Geocaching Travel Bug® comes as a pair; one bug gets attached to an item (or on its own) and the other is a copy that you can hold on to. Geocaching Travel Bugs® have a unique tracking number stamped into the metal tag. The tag was designed for durability.
