The You're a Winner! client program runs on a computer running Windows 7 or later versions. When the program starts it displays a customer signup screen that displays the QR code your customers can scan to either sign up or sign in.
Alternatively, if you want to present the QR code at the table (in a restaurant or similar setting) you have two options.
First, the client program has a menu item labeled Tent Cards that allows you to print table tent cards with the QR code included in the layout. The layout itself is user-definable so you can include your own logos and messaging on the card. A sample of a tent card appears below.
The You're a Winner! client program also provides a simple web server interface that can be accessed by a tablet computer or cell phone on the same subnet as the computer running the client program.
