ACI Worldwide entered an agreement with Worldpay Inc. to drive the acceptance of alternative payment methods by merchants in international markets. 

Worldpay, a London-based payments processor, will use ACI's Up e-commerce payments solution to broaden the number of alternative payment methods that merchants can use in various markets. 

"Working with a proven leader like ACI Worldwide not only enables us to offer our clients fast and seamless access to a growing number of APMs in new markets, it allows Worldpay to focus even more on developing new innovative services and technology solutions," Asif Ramji, chief product and marketing officer at Worldpay, said in a company release. "As more of our merchants expand into cross-border and cross-channel trade, offering local payment types that are recognized, trusted and utilized by consumers is an increasingly important factor for business success."
