Abstract: A method and system is provided for establishing credit on an automatic vending machine or vending device. A currency amount or a number of credits is established on a vending device in order to obtain a product, service or access time from a vending device using a cellular telephone, or other personal wireless communication device. The personal wireless communication device activates an applet, which may be downloaded at the site, to establish a link with a vending machine universal wireless interface coupled to the vending machine device controller and also establishes a link with a remote server for authorizing credit for a vending transaction, which allows the vending transaction to take place.
