Abstract: A method and system for displaying a virtual PIN pad and a virtual non-PIN pad on a touch screen having a screen area. Electronics in electrical communication with the touch screen are operative to provide the virtual PIN pad on the touch screen in a payment mode and provide the virtual non-PIN pad in a non-payment mode. The virtual PIN pad has a first plurality of virtual buttons and the virtual non-PIN pad has a second plurality of virtual buttons, the first plurality of virtual buttons being greater than the second plurality of virtual buttons. The electronics are operative in the payment mode to render the virtual PIN pad having the first plurality of virtual buttons and determine a numerical sequence entered by a user at the virtual PIN pad. The electronics are operative in the non-payment mode to render the virtual non-PIN pad having the second plurality of virtual buttons determine selections entered by a user at the virtual non-PIN pad.

Abstract: A vending machine user interface can include a first controller operatively connected to an input device capable of receiving payment or account information. The first controller can, with another device, via a second controller, or otherwise, allow secure communication of data from the input device. The first controller, in this regard, can control the communication between the input device and the other device to protect the input device from unwarranted communication from the other device. The first controller can establish a secure channel with the other device using encrypted communications. The first controller, second controller, etc. can be connected to independent printed circuit boards (PCB). Activation of sensors connected to the PCBs can cause the first and/or second controllers to erase data necessary to ascertain/decode communications from the input device, such as encryption/decryption information, or may otherwise decommission the input device or a portion thereof.
