so a lot of the commercial accounts we maintain are now requiring us to take credit cards, so they can speed up the process and keep better track of their payments. i have a buddy that runs a credit POS company, so we have a portable POS machine. other than the 3% we get dinged every time we slide a card, does anyone have any other negatives about taking cards??? i have some customers that want us to just run their card every month, but i am leary of keeping peoples card info on hand. i dont want that liability. does anyone have a form they make customers sign prior to keeping card info??? wanna share it??? any info is helpful, thanks,.
