With the SumUp Solo 4G mobile card reader + charging dock, you get a convenient and modern way to accept payments. Whether you're in a café or at a market, your card reader always stays connected. It automatically connects to the internet via the built-in SIM card. To register, you can simply enter your Chamber of Commerce number. On the touchscreen, you enter the amount, and customers choose whether they want to leave a tip and how much. The device accepts debit cards, credit cards, and smartphones with Apple Pay or Google Pay. For each payment in Germany, you pay 1.39% in transaction fees, with no contract or minimum revenue. You decide when and how often you use the SumUp card reader. This way, you stay flexible whether you process payments every day or only accept payments now and then.
