Abstract: A coin mechanism has one or more coin tubes for storing, respectively, coins of one or more denominations, a dispenser for controlling the dispensing of coins from the coin tubes, and a coin mechanism controller suitable for connection to a controller in an automatic transaction system so as to receive change dispense signals from the automatic transaction system controller indicating the form of dispensing change to a customer. The coin mechanism controller, when connected to the automatic transaction system controller, serves as an interface between the automatic transaction system controller and the dispenser, and is programmed to re-determine the form of paying out the change, for example, by taking into account the distribution and denominations of the coins in the coin tubes. The arrangement of coin tubes in a coin tube cassette for use with the coin mechanism can be identified by entering a code on a keypad associated with the coin mechanism.
