With our partnership with Square you can process credit card transactions via iOS & Android using PHP Point Of Sale. Square has fixed pricing and no contracts! Their rates are published on their website.
Square works in many countries including the United States, Canada, Australia, and the UK.
The integration couldn't be easier! Connect the location to Square first, then install the Square Point of Sale application alongside PHP Point Of Sale — or pair a Square Terminal to a register with a Square Device Code under Locations → edit the location → Registers & Terminals.
