How to use QR codes for business and the office
QR codes are the main bridge between the physical world and digital services. In an office, the most practical use is a printed sign with a Wi-Fi QR code so guests can connect instantly — the phone joins the network when the camera is pointed at the code, with no need to type a complicated password. All codes are generated right in your browser with the error correction level you choose: pick Q or H for printed signs so the code still scans when the printout is worn or partly covered. For large-format printing, download the SVG.
