IDT Finance is offering retailers Europe's first over-the-counter prepaid MasterCard, available through E-pay and PayPoint.
The agreement enables retailers with terminals to sell the disposable Prime Cards to customers over the age of 18.
The cards can be bought as gifts and used for secure payments. They are available in a choice of one-off denominations ranging from £10 to £150 - each with an additional purchase cost of £3 per card.
E-pay commercial director Andrew Dellow said: "We are delighted to launch the IDT Prime Card to our retailer estate nationwide. The card is perfect for consumers without bank accounts, who have no permanent address, or who simply want to keep track of their spending and reduce exposure to debt."
