Accepting card payments in Europe as a UK-based band

I've seen that this question was asked years ago but I wanted to see if there'd been any updates to it. Basically I'm looking for a way for our band to accept card payments for merch in Europe as a UK-based band. We tried using a QR code link to Paypal when we recently toured Belgium but found most people didn't have Paypal.

In the UK we use SumUp but as I understand it, card reader's bought in the UK won't work abroad.

Does anyone have any recommendations?
