What is needed for a user to scan a QR code?

To scan a QR code, a smartphone equipped with a compatible application is essential. Modern smartphones come with built-in camera functionality that can interpret QR codes when appropriate software is used. Many smartphones include QR code scanning capabilities directly within their camera applications or through dedicated apps. This process enables users to quickly and easily access information encoded within the QR code, such as URLs, contact details, and text.

While other devices like tablets or computers may also be used to scan QR codes, they typically require additional equipment or software not as readily integrated as in smartphones. Thus, relying on a smartphone with a compatible application provides the most practical and user-friendly solution for scanning QR codes efficiently.
