The consumer page.
On the customer's own phone, over your guest wifi. No app, no login, no account to create and no password to forget. It carries your store's name. They scan a window sticker, a Monroney, a VIN, a QR code, or a stock number, and that car lands in their own list. The system gives them a code instead of asking for a name, and it asks the harder questions while they browse. It works in the service drive too.
