Instead, after entering her driver’s license number and bank account information online with a two-year-old company called National Payment Card (NPC), she’d be able to pay for gas just by swiping her driver’s license (linked directly, via the existing magnetic stripe, to her bank account), and entering a personal identification number.
If this catches on, it should benefit gas buyers everywhere. The fact that you could pay with a drivers license might rid the need of another card in your wallet, and because the gas stations will save money, they pass those savings on over to you.
