Nick Ogden developed the multi-currency processor in Jersey in the 1990s before selling it to RBS in 2002.

WorldPay was one of the assets RBS was told to dispose of by the EU competition watchdog earlier this month as a condition for joining the UK government’s asset protection scheme.

It is one of the leading payment processing businesses globally and could have a price tag of around £1.5 billion.

Mr Ogden, who went on to develop a voice-verified identification system for mobile and internet payments after selling WorldPay, said that he had backing from private equity firms to finance the deal.
