Abstract
Fuel dispensing transactions may be accomplished by a variety of systems and techniques. A fuel dispensing device may include a payment module, a data entry device, and a customer display. The payment module may receive a first communication from a point of sale device requesting an encrypted response and receive a second communication from the point of sale device requesting an unencrypted response. The module may match the first communication to a first corresponding library entry, match the second communication to a second corresponding library entry, determine a user response based on one of the first corresponding library entry or the second corresponding library entry, where the user response defines one of the encrypted response based on the first corresponding library entry or the unencrypted response based on the second corresponding library entry, and use the corresponding library entry to generate a visual customer display requesting the user response.
