MasterCard said it had agreed to buy 92.4 percent of the UK-based VocaLink Holdings for about $920 million (£700 million) from Barclays, Royal Bank of Scotland and the Co-Operative Bank, after adjusting for cash and certain estimated liabilities.
VocaLink operates payments technology platforms on behalf of UK payment schemes.
A majority of VocaLinks shareholders will retain a 7.6 percent stake in the firm for at least three years, according to the terms of the deal, MasterCard said.
VocaLink's existing shareholders could get an additional $220 million, if certain performance targets are met, MasterCard said.
