An open source standard to secure the circulation of physical items such as cryptocash. It allows to checking the integrity of physical cryptocoins without having to break their sealing, like checking a banknote under a UV blacklight. Thus, they can circulate safely, by hand from peer-to-peer, until they eventually get cashed by having their irreversible sealing opened, then trashed. Checkoin Coins present a Visible Scan Data on their outer surface. When a user gets a Coin handed to him/her, the user Scans the Visible Scan Data of the Coin with a blacklight application (or device) to check the Coin. Still under development.
