QR Code Check-In is a method where visitors scan a Quick Response (QR) code using their smartphones to access the digital check-in form. This contactless approach is convenient and hygienic, especially important in contexts where minimizing physical contact is desired. It also allows for seamless integration with mobile devices.

This is used primarily by digital sign-in solutions transforming the traditional pen and paper sign-in sheet into an app that can be used by visitors on their own phones.
