The Kartcoin is the ‘coin for keeps' . It means your customers will never be caught without a $1 coin for their shopping cart again. The token easily detaches from the keyring and is inserted into the Kartlok in place of the coin. When the user returns the cart, they get their Kartcoin back, snap it on the keyring ready for the next use. The Kartcoin 'coin for keeps' features a quality metal keyring with a painted zinc alloy token. They have a durable enamel finish and are available in any pantone colour.
