In-N-Out Apple Pay is now one of nearly 700 other places that take Apple Pay. You can add your In-N-Out card from their website, which means you can scan and pay for your next burger even before you pull into a parking spot. The service works with all major credit cards, as well as rewards cards and gift cards which you'll still have to load into Passbook. But at least it's another option for your digital Wallet. All things considered, that could mean less time spent at cash registers and more time spent eating In-N-Out burgers.
