Car wash owners are looking for a way to provide a monthly wash plan program that does not require an employee to install an RFID sticker in customers’ cars and provides a self-service management portal for the customer. This portal eliminates the wasted time operators spend managing their pass program as most everything is now automated. In addition, Dencar Technology created a Vehicle Identification Automation (VIA Guard) technology that links mobile phones to vehicles ensuring 1:1 use of the wash membership pass tied to the user’s car. This allows tunnel operators to dramatically reduce operating expenses and unattended operators to join the monthly wash pass revolution without fear of fraud. Selling wash passes has never been easier and adds less than 10 seconds to a typical transaction using a Dencar pay station.
