WorldPay (formerly RBS WorldPay) is a payment processing company. It provides payment services for mail order and Internet retailers, as well as point of sale transactions. Customers are a mix of multinational, multichannel retailers, with the majority being small business merchants. WorldPay started as an electronic payment provider called Streamline in 1989 in the UK but has extended into mail order/telephone order, "unattended" payments and handling secure payments over the Internet through merger and acquisition of several other companies.[1]

WorldPay first provided Internet payment services in 1994, making it one of the first providers of such services in the world.

It was acquired in 2002 by Royal Bank of Scotland (RBS) which renamed the business RBS WorldPay. RBS expanded the business significantly by acquiring and merging a number of payment solutions companies from different countries. Over the next five years it was combined with seven leading retail payment solutions brands: Streamline, Streamline International, PaymentTrust, Netherlands based Bibit, RiskGuardian and US based Lynk. By 2007, WorldPay was the largest merchant acquirer in Europe and one of the largest globally, operating in more than forty countries, 120 transaction currencies and fourteen settlement currencies. That year WorldPay processed 4.4 billion transactions worldwide.[2]

As a condition of the European Commission's clearance in December 2009 of state aid to RBS, WorldPay was to be sold as part of divestiture plan that was agreed. On 6 August 2010, Advent International and Bain Capital agreed to acquire WorldPay for £2.025bn including a £200m contingent consideration. The RBS group retained a 20% stake in the newly-independent business[3] with Advent International and Bain Capital owning 40% each. The sale completed on 1 December 2010. RBS WorldPay was renamed WorldPay as part of the deal.[4]

On the 21st December 2010, almost immediately following on from the sale, WorldPay acquired Cardsave, one of the UK’s leading independent sales organisations distributing credit and debit card processing services to small retailers.[5]

WorldPay continues to expand rapidly. In May 2011 WorldPay acquired Envoy Services Limited, a leading provider of alternative payment solutions to eCommerce merchants worldwide, for an undisclosed amount.[6]
