What is a QR code and how does it work for WiFi connections?
A QR code, or Quick Response code, is a two-dimensional barcode that can store information in a scannable format. When you generate a QR code for a WiFi network, it encodes essential details such as the network name (SSID) and the password. Users can scan this code using their smartphone’s camera, which then automatically prompts the device to connect to the specified WiFi network without the need to enter the password manually.
QR codes work by triggering an action on the device that scans them. When your smartphone recognizes the QR code as a WiFi network invitation, it decodes the information and typically provides a prompt to connect. This simplifies the process of sharing network credentials, making it an efficient method for connecting multiple devices without the hassle of typing in complex passwords.
