The Vcard system runs independent of the car wash controller / P.O.S system. That means you don't have to replace your current tunnel controller to implement Vcard. This is a huge savings and makes the Vcard system the most cost effective card system in the car wash industry.
The best way to implement the Vcard program at an exterior automatic car wash is to use a wireless hand held and a mobile receipt printer. this allows the attendant to be mobile and increases the speed of the transaction, allowing more cars to be processed more quickly through the car wash.
