The partnership between the two companies means that the iPad-based cash registers provided by Revel Systems now will be able to process both debit and credit card payments.

Revel Systems hopes that SumUp‘s technology will enable the company to expand into Europe, where the ability to process cards is critical. Revel currently has more than 100 store chains and restaurants in North America, Australia, and Saudi Arabia using its point-of-sale platform.

Called a “European Square”, SumUp is focused on building technology that will bring cashless, point-of-sale commerce to small businesses. All the merchant requires is SumUp’s portable card reader and the iOS or Android app, and they are ready to accept card payments on their mobile device.

SumUp was founded in 2011, and is headquartered in Dublin, Ireland. The company has raised $20 million in funding, and recently announced that it had added American Express cards to the range of cards SumUp can process.

SumUp was one of the companies that demoed their technology as part of FinovateEurope in February. See them in action at our FinovateEurope video page here.
