Stamp Identifier is an app that uses advanced image recognition technology to identify stamps and provide more information about them. The app is powered by colnect.com, a social network for worldwide collectors that has the world's largest online stamp catalog and a marketplace for buying and selling stamps. Users can use their camera, choose an image from their gallery, or share an image from any website to find their stamp.

To ensure accurate results, users must fully crop the background and ensure that the image quality is not poor. If a stamp is not recognized, users can use the "Not found?" feature to receive assistance from a human who will provide tips on how to improve search results. The app also allows users to save a list of favorite stamps for later review.

Stamp Identifier is a useful tool for stamp collectors or anyone curious about a stamp they come across. With its advanced image recognition technology and access to Colnect's extensive worldwide stamp catalog, users can easily identify and learn more about their stamps.
