I looking into Wickets vs everything else and found that Wickets was better overall. I was going to put CC readers in each bay but decided to put one on the Wicket dispenser. That way CC users would still be able to wash they would just have to get a Wicket first. I can keep up with who my repeat customers are and reward them for staying loyal.
I have more than one wash and own a laundry. I can have the Wicket work on one, some or all my locations. I like having that option available. My customers earn points when they use their Wicket and can later trade in points for free washes, wax, hats, t-shirts, etc. It's a great way to market.
