The card, which has an eight-week interest-free period and an annual interest rate of 13.9%, is aimed exclusively at sole traders. There is a £25 annual fee.

The card is running a reward scheme offering free fuel, depending on how much users spend.

Spokesman Colin Roberton told This Is Money:

"Many sole traders don't keep their work and personal spending separate.

"It may seem simple to put them both on the one card, but it can be tricky trying to untangle them when the tax return is due."
