Cleaning cards provide a fast, economical and simple means of cleaning your bill counter. The patented Waffletechnology removes dirt, dust, oils and other contaminates from bill counters that can cause misfeeds or jams. A card cleans the entire rounded surface of magnetic heads with 10 times higher cleaning pressure and a design that reaches recessed sensors. These Waffletechnology cards are flexible and have raised platforms on their top and bottom surfaces that spring up and down reach every nook and cranny in your bill counter.
