Digital signage is a type of electronic display that uses LCD, LED, or projection technology to display content such as images, videos, and text in public spaces. It can be used for advertising, information sharing, and entertainment purposes.

QR codes can be integrated into digital signage to enhance its capabilities. By including a QR code on a digital sign, viewers can scan the code using their smartphones and access additional content or information related to the message on the screen. For example, a digital sign in a museum could display information about an exhibit and include a QR code that, when scanned, directs viewers to a website with more detailed information about the exhibit. Or a digital sign at a restaurant could display a menu with QR codes that link to more detailed descriptions of each dish, nutritional information, or the option to order directly from a mobile device.

QR codes can also be used to gather data and feedback from viewers. By including a QR code on a digital sign, viewers can scan the code to access a survey or feedback form, providing valuable information to the organization or business running the digital signage. Overall, digital signage with QR codes can enhance viewer engagement, provide additional information and interactivity, and enable data collection and analysis.
