Gate gas stations, at least in the Concord, NC area, insist on using the bank billing zip code for a debit card transaction at the pump, rather than the card holder’s PIN number. I do not see how this is beneficial to card holders, as it seems to be a much less secure number to require for gas purchases. If a card is lost at a gas station, a person should just swipe it at the pump and use the gas station’s zip code, or a few surrounding zip codes until he/she guesses the right number. I don’t know the statistics, but I would guess that the majority of people filling up at gas stations are local, meaning the requirement of billing zip codes, rather than requiring a PIN number, is ludicrous.
