Abstract: Disclosed is a system and method for enabling cashless purchases at a vending machine. A conventional vending machine may be modified by attaching to it a Bluetooth transceiver that can communicate with a mobile telephone's Bluetooth interface. The vending machine's Bluetooth interface may be connected to an MDB bus to communicate with the vending machine's VMC processor. The VMC processor may be reprogrammed so that it can poll the vending machine's Bluetooth reader. The VMC may then poll the Bluetooth interface to detect a payment signal sent by the mobile telephone and deliver and item, ordered through the mobile phone's graphical user interface, to a customer.
