This is already an issue for tourists in many countries that have their own payment system (e.g. Brazil, India, Singapore, Thailand). In some of them you have companies that came up with products for tourists that allow them to pay but they usually come with fees. From what I know the majority of tourists in these countries just travel with cash.

I had that issue in India and it was definitely annoying.

I've never had a problem paying with cards in Singapore or Thailand, although it's been a few years since I've been to Thailand.
