Yes, our app does work for merchants/businesses in most countries in Europe.
We currently accept a number of payment schemes such as Apple Pay, Google Pay, Visa, Mastercard, American Express, AliPay, WeChat Pay, Bancontact, and iDeal, so you can accommodate all your customers.

If someone pays from the US for example, the bank that issued the card will convert the amount into USD automatically for your customer while you will receive the money as usual in GBP.
