NEW YORK (AP) — Want to leave your barista a tip? Starbucks is making an app for that.

The Seattle-based coffee company says a digital tip function will be added to its mobile payment application starting next summer. A similar option will also be available on Square, a new payment app that Starbucks customers will be able to use starting in November.

To use either of the programs, customers download the app then link a credit or debit card to the account. When it comes time to pay at the register, they open the app and wave their phone in front of the scanner.

The Starbucks app can only be used at the company’s cafes. The Square app can be used wherever it is accepted.
