Who are we?

We are the leading mobile point-of-sale (mPOS) company in Europe. We started out and built our payment service from scratch to shake up the industry and wake up the entrepreneur within anyone. We created a unique device that with the smartphone that’s in your pocket, allows small merchants to accept card payments anywhere. From our paperless onboarding to taking the first payment, we make it easy. Traditional offerings leave out small businesses, we don’t. We are open and honest about our pricing and have no hidden fees.
