Mastercard today announced a major expansion of its long-standing relationship with General Motors (GM). Customers at more than 4,000 Chevrolet, Buick, GMC and Cadillac dealerships in the United States, as well as online customers, will soon be able to order and pay for ACDelco and other service parts, accessories such as Chevrolet Performance Parts, Maven car-sharing services, OnStar guidance, security and data plans, and over-the-air updates for OnStar Go using Mastercard’s payment gateway. The gateway enables fast and secure electronic credit and debit card processing.

The new platform builds on the successful relationship GM and Mastercard have forged with the GM Rewards Card program. Since 1992, cardholders have earned rewards to help purchase more than 7.3 million cars, trucks and crossovers. The payment gateway solution draws on the Mastercard network for its global connectivity to enable payment acceptance from all brands via digital channels.

“Working with Mastercard will help us deliver the best possible customer experience by aligning all of our business units and dealers under one payment gateway that is fast, secure and has global scale,” said Ed Vogt, GM’s director of e-commerce, U.S. sales operations.

“As a global transportation company, GM committed to a digital roadmap that enables e-commerce at every point of engagement with franchisees, providers and customers. Mastercard is pleased to provide the network coverage and payment gateway that offers the benefits of centralized management at headquarters with the flexibility of meeting the needs of individual business outlets,” said Tim Fletcher, senior vice president, Payment Gateway Services, Americas, Mastercard.

Along with the BuyPower credit card portfolio, other collaborations between Mastercard and GM include OnStar Go, the new cognitive mobility platform that enables drivers to pay for everyday errands such as picking up family dinners or filling gas tanks from the comfort of GM their cars. OnStar Go is powered by Masterpass payment technology and Mastercard Digital Enablement Services (MDES) and featured in many GM cars starting this year.
