Paerpay is the best payment experience for restaurants and their guests | More than ever, merchants like restaurants need help to adopt contactless payments, especially restaurants with old legacy POS systems. These restaurants are struggling to implement new payment standards because their old POS systems don't offer a reliable and integrated solution that is cost-effective and easy to use. Paerpay provides restaurants with a contactless payment solution that does not require them to change their hardware or credit card processor.
