Each tag features a unique QR code that takes you directly to the the item's trackable page on Geocaching.com. Just scan it...log it.... and keep it moving. A Geocaching QR Travel Bug® is a unique tracking tag that you can attach to items and give them goals for others to try and complete! This does not replace the classic Travel Bug® but simply is in addition to our existing product line. 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.
