American Express is expanding its Serve platform, this time to Verizon Wireless customers. Amex and Verizon announced they will integrate Serve, American Express' digital payment and commerce platform, onto mobile devices on the Verizon network.

The companies said that Verizon customers will be able to establish Serve accounts enabling them to make payments and redeem offers for goods and services directly from their mobile phones and tablets using the Serve platform.

"Our collaboration with Verizon highlights the speed at which Serve is evolving to reach a wide audience," said Dan Schulman, group president for enterprise growth at American Express, in a statement.

According to the announcement of the new agreement, Verizon Wireless customers who use Serve can buy goods and services online through their mobile devices with a simpler process, while merchants accepting Serve mobile payments will have a streamlined option for processing and settlement.

"Serve provides a quick and intuitive way for our customers to use their mobile service in a refreshingly convenient way," said Greg Haller, president, enterprise & government for Verizon Wireless, in the announcement.

The companies said they will also collaborate to source, distribute and simplify redemption of online and mobile offers with participating merchants through the use of the Serve account, including automatically crediting coupons and offers directly to Serve accounts.

The announcement said that Amex and Verizon are working with Payfone to support Serve checkout on Verizon Wireless devices.
