75% of Credit Card Reader failures are due to dirty terminals, it’s important to keep the terminals free of dirt, dust, and oils introduced from the environment and normal use.  A working credit card terminal results in a successful sale and a hassle-free transaction.

Cleaning cards are used for the purposes of preventing expensive maintenance and replacement costs of credit card terminals, while ensuring overall efficiency and reliability eliminating or minimizing failed transactions, that result in frustrated and unsatisfied customers.

The ParkingZone sells terminal and bill acceptor cleaning cards that use Waffletechnology®, these cleaning cards incorporate flexible, raised platforms on their top and bottom surfaces. These cleaning platforms are essentially spring-loaded, significantly increasing the pressure applied to the internal components as the card passes through the mechanism. The platforms actually spring up into surface cavities to clean recessed sensors, and the leading and trailing surfaces of rounded optical lenses are effectively cleaned and not just the tip of the optical reader.


Card readers can be found in a number of varieties, including EMV smart card (chip and pin) readers, POS credit and debit card readers, ATM card readers, mobile payment solutions and access control/hotel door locks

Bill acceptors accept and validate paper currency using optical lenses and magnetic sensors. Bill acceptors can be found in a variety of models such as banknote acceptors, payment kiosks, self-checkouts, bill validators, vending machines, slot machines, safes, ATM deposits, and counterfeit detectors.

Most manufacturers recommend that the print head of the thermal printer be cleaned often, removing carbon buildup and ribbon dust that may collect over time. Regular cleanings will prevent you from having to replace the thermal printer head, which is the most expensive replacement part on a thermal printer.

Print-head cleaning pens are a great option for simple touch ups. To use, press the pen tip to the print-head and move from side to side. If possible, use the cleaning pen on the rollers too. Your cleaning pen may be good for approximately 10 uses, or until it shows sign of dirt buildup. Regular cleaning will ensure that you continue to receive consistently excellent printing results while also preserving your print-head from premature failure.
