The price of SumUp POS Lite + Solo has risen by a good 50% in the last two weeks. Not bad for a cash register with which you can't even use a scanner. This cash register is useless for any more demanding applications. If you don't have a lot of articles and changes to deal with and don't process customers every minute, this till might be something for you. The costs that you have to pay to Sumup are also far too high!
