Probably?... I opened mine years ago for ebay (when I had propper credit cards and debit cards) and left it Idle for 5 years, then recently and added my Solo cashpoint card to it and it works fine
Solo cashpoint card IS debit card, widely accepted these days, by many retailers.
i found out in january sales that Monsoon don't accept it, luckily i had enough cash with me, would look like right plonker having to go to cash point to take money out and back to the shop, don't think I'd bother.
Last year sainsbury's didn't accept solo card and I emailed them about it, as probably many others did, few months later they started accepting Solo.
