Coiner – a high-level verification

This app was designed on commission for an individual client and coin collector for the benefit of anyone passionate about coin collecting.

The apps creation is designed for the purposes of authenticating gold and silver coins. The coin appraisal process itself is based on the unique sound effects of each coin being spun. After recording the sound of the spinning coin, the app compares the data with a stored collection of genuine coin recordings. The app then provides a visualised diagram mapping the similarity of the sound recorded from the collectors’ coin with that of authentic coin from the database- thereby enabling an estimation of the coin’s authenticity to be provided from Coiner.

The app has been developed for iOS devices and serves as an excellent example of the unconventional usage of the variety of sensors and great processing power within iPhones and iPads.
