Method and apparatus for controlling access to or from a parking lot associated with a retail or other sales facility. The parking lot has an automatically operated, normally closed access gate and an optical scanner. Patrons may access the parking lot free of charge by displaying purchased merchandise such that the scanner reads a bar code inscribed upon the merchandise. Data corresponding to the scanned bar code is compared to data entered into the memory of an automated data processing device. If that comparison results in establishing a correlation between data from the scanned merchandise and data entered into memory corresponding to merchandise stocked by the sales facility for vending, then a control signal is generated and transmitted to the access gate. The access gate then opens and allows the vehicle submitting merchandise for scanning to access the parking facility.
