Player tracking card readers, like all card readers, use a magnetic head to read the stripe on your patron's card. Each time a player card is used, the card carries dirt and dust from the environment as well as oil from your patron's fingers into the card reader. These contaminants eventually build up and cause the card reader to fail.
The Waffletechnology Card Reader Cleaning Card is an improvement on a staple product that has been cleaning card readers for 20 years. The unique cleaning waffles remove dirt and contaminants from the sensitive read heads inside the card reader. This product can be used as a corrective cleaner, but is best utilized as a preventive maintenance item. Use this product as a standard cleaning item to keep your card readers functioning as designed.
