Verizon Wireless today said it will integrate Serve, a next-generation digital payment and commerce platform from American Express, on a variety of Verizon mobile phones and tablets.

Over the coming months, Verizon Wireless customers will be able to establish Serve accounts that will enable them to make payments and redeem offers for goods and services directly from their mobile phones and tablets.

Serve allows users to authenticate a mobile number, enabling a customer to make a purchase on-screen.

American Express and Verizon Wireless also will collaborate to source, distribute and simplify redemption of online and mobile offers with participating merchants through the use of the Serve account. For example, as customers redeem certain offers or coupons using their mobile phones, the credit may automatically appear in their Serve account.

The two companies are also working with Payfone to support Serve checkout on Verizon Wireless devices. Payfone’s pre-authorization and intelligent routing features will help Verizon Wireless customers who use the Serve application to make mobile payments.

Verizon Wireless is part of the joint venture Isis, which aims to create a national mobile payments network through the use of technologies like NFC. AT&T and T-Mobile are also part of Isis.

“Our commitment to building the entire mobile payments ecosystem, through our Isis joint venture and now with Serve, gives customers incredible new ways to use their mobile devices,” said Greg Haller, president of enterprise and government for Verizon Wireless, in a press release.
