The card terminal is 1.49% and costs GBP 0 to start. The three point-of-sale tiers all run at 1.69% and differ only in what you pay up front for onboarding and installation: GBP 995 for mobile POS, GBP 1,495 for POS Pro and GBP 2,495 for POS Premium. Every one of those four prices is labelled "Below GBP 200,000 in annual card turnover".
