I have the ExpressKey system in my wash for my business customers to charge their washes and I bill them at the end of the month. I also take credit cards using CryptoPay in the self serve and Hamilton in the automatic. I am looking to upgrade to a card system or something new for loyalty and billing. How do I get a loyalty billing card to work with both CryptoPay and Hamilton systems? I don't really want to switch to all Cryptopay as my customers like getting a receipt at the auto cashier at time of purchase and CryptoPay doesn't offer that. Anyone have any suggestions?
