Lots of companies are working on ways to use smartphone payments to streamline the ordering process. PayPal’s entry into the market is particularly interesting, since so many people have a PayPal account already. Plus, their app isn’t tied to ordering from a specific establishment (like paying with your phone at Starbucks). Instead, PayPal’s app could let you order just about anywhere.

From the customer side, the app is called PayPal Wallet. The merchant app is PayPal Here, which lets merchants accept and send money.

So how would it work? Check out the demo video below from SXSW. You use your phone to “check-in” at a destination, which automatically lets a merchant start a tab for you. The example below is ordering drinks, but it’s easy enough to imagine lots of possibilities for the app in the future!
