When doing research for card readers for spice tools, I came across a GitHub of someone's IOS app that lets an iPhone be used as a card reader for spicetools (Helloyunho/real-card: Use your iPhone as an Amusement IC (or e-amusement card) reader in Spicetools. (github.com))
It requires a connection to some server to work, as it asks for an IP/domain name, port, and an optional password. I have been trying all day to figure out what to do here and if anyone has gotten it to work, id much appreciate some help.
