For a while now i have been preparing for the opening of my boba cafe in my little city, one of my focuses of the business was to make it very mac friendly as there is not a very huge mac using public, but its growing. I really want to use 2 iMac g4's for my registers, but im having a bit of a problem with hardware and software to run everything with. I've found 6th sense cafe, tried it a bit, cant really try other hardware like receipt machines and cash boxes as i havent bought them yet. But does anyone have any sort of experience with macs as a pos machine. I'd really hate to use a windows machine to handle my pos because it would be detrimental to the image i want for the place. But i want the best solution possible. Any comments? Suggestions? Maybe this is a hardware issue? Mods feel free to move.
