The customer service is excellent! They always respond quickly with questions and resolve issues as needed. I love how easy it was to set up my first card and then add more cards later if need be. There's nothing really i dislike about this program but the fact they don't have any rewards programs like cash back credit cards in their portfolio. I would highly recommend them to anyone looking for an awesome loyalty program. We've been using QR Loyalty Rewards Cards since we started our business. It has made collecting points much easier than traditional punchcard systems and there were no problems at all when setting them up. So far so good.
