An online payment system PayPal is forecast to have a major boost as mobile payment systems are increasingly growing, says a new survey from market research firm GfK.

According to the research PayPal is the brand most likely to be trusted with personal financial data by consumers in nine major markets around the world.

Credit-card brands Visa and MasterCard were the next most likely global brands to be trusted, followed by Apple -- which already handles account data through the iTunes store --, Nokia and Samsung.

Mobile operators, who have been hoping to diversify their increasingly commoditised revenues through NFC, came far down the list.
