How to use the Car Listing QR Generator
One code per car
A forecourt buyer wants the full story on one car, not a search page. The code opens that car's listing, with the price, mileage, and VIN already in front of them. Generate one code per vehicle, and use the listing URL for that specific car. A code that opens the dealer homepage sends the buyer back to searching, which is exactly the friction that loses sales after hours, when nobody is there to help.
The VIN is the check
Buyers use the VIN to check history, recalls, and whether the car in front of them is the car in the listing. Print it in plain text beside the code, in capitals, exactly as it appears on the vehicle plate. This tool checks that a VIN you enter has 17 characters using only the letters and digits a real VIN allows. If the VIN on the car and the VIN on the card disagree, fix the card before the car is shown to anyone.
Testing and removal
Print a sample, scan it, and confirm the listing that opens is the right car at the right price. Test under forecourt lighting, including at night, and keep the quiet zone around the code. The moment a car sells, take its card down and update the listing page to say so. A stale code on a sold car sends buyers to a listing that no longer exists.
