Ok so I'm just revisiting this as I'm ready to go ahead with the plastic loyalty cards now... This may be a silly question (I blame the wine!) but if you get the magnetic strip cards printed, is each strip different so it brings up how many points each client has through the software that comes with the card reader? And then you just add/remove points in the software? Can anyone recommend a company that does the cards and the card readers to go with them? I'm worried I'm gonna buy a card reader that doesn't work with the cards I order! Thanks in advance! x
