WOONSOCKET, R.I. — CVS Health recently announced the launch of CVS Pay, a mobile payment app that is designed to expedite the checkout process at the pharmacy counter and the front of the store.

The company said the tool integrates payment, prescription pickup and ExtraCare loyalty card functions in one scan at the checkout.

CVS Pay is currently available in selected stores in New York, New Jersey, Pennsylvania and Delaware. A nationwide rollout is expected to kick off later this year.

“Over the past year, our digital team has brought to market numerous new digital tools like CVS Pay that make shopping at CVS Pharmacy easier and more convenient,” said Brian Tilzer, the company’s senior vice president and chief digital officer. “We’ve been excited by the level of customer adoption of these digital solutions, and we will continue our quick pace of innovation and deployment to make our customers’ health care experience even easier.”

To use CVS Pay, customers add their credit or debit cards in the CVS Pharmacy app. At the register in a CVS Pharmacy store, they show the checkout clerk the barcode in their app. The clerk then scans the barcode and rings up the purchases, and the customer selects a payment method from those stored in the app. The payment is then processed. Once the transaction is completed, the customer will receive a confirmation of payment in the app.
