EidThere are several venders that offer a hybrid payment system that are significantly more cost effective that $700 per machine. I have used several different options in my stores and none off them are perfect, and some are only barely marginal. I will not go into the specific ones that I have used but I will tell you that some are better than others - plus if you are close to retooling your store pretty much every manufacturer is now offering app based CC pay on every machine. As far as WDF service CC acceptance there are multiple options that include a POS that is designed specifically for that service.I would suggest that you look for a system that is more cost effective than $700 per machine - maybe on that is App based with a kiosk for central pay if the customers don't want to download the App. Those systems tend to be much cheaper and from my experience they are just as effective as a system that has a CC reader on each machine. I have both types of systems and both stores are running about 20% CC usage (the system with the readers on each machine is about 3-5% higher usage) but the costs of purchase for the app system was about 25% of the cost of the system with readers on each machine. Plus the monthly and yearly costs along with the processing fees were MUCH lower for the App system.
