Virtual pin pad for fuel payment systems

摘要

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.

主权项

1. A fuel dispenser having a user interface configured to facilitate transactions, the dispenser comprising:
a touch screen having a screen area, wherein the touch screen comprises a plurality of detection locations; and electronics in electrical communication with the touch screen, the electronics operative to provide a virtual PIN pad on said touch screen having a first plurality of virtual buttons sufficient to present an entire PIN pad and, when displaying unsecure content during which receipt of PIN information is not permitted, provide a second plurality of virtual buttons less than that required to present an entire PIN pad; said electronics being operative when receipt of a PIN is permitted to:
render said virtual PIN pad having said first plurality of virtual buttons, said first plurality of virtual buttons comprising at least ten of said virtual buttons; anddetermine a numerical sequence entered by a user at the virtual PIN pad; said electronics being operative when displaying unsecure content to:
render said second plurality of virtual buttons, said second plurality of virtual buttons comprising no more than eight of said virtual buttons; anddetermine selections entered by a user such that a fake PIN pad cannot ascertain the user's PIN when unsecure content is being displayed.
