QR Codes guides

Practical, no-fluff guides for getting the most out of your QR codes and barcodes.

QR Codes for Zoom Meetings: Skip the Meeting ID and Passcode

Reading a 10-digit meeting ID and a passcode off a screen or invite is exactly the kind of manual entry a QR code exists to eliminate.

A YouTube QR code opens straight into the app when the scanner has it installed, skipping the browser entirely for a smoother viewing experience.

WhatsApp is the default customer support channel in much of the world. A QR code gets someone chatting with you in one scan, no typing your number.

A printed instruction sheet can only show static pictures. A QR code on the same sheet can hand someone a video instead.

One UPI QR code works across every major Indian payment app — no need to display five separate codes for five different apps.

A conference badge, a TV lower-third, a printed flyer — anywhere someone can't easily type your handle, a QR code gets them there instead.

TikTok has its own in-app QR scanner for exactly this, but a QR code you control works everywhere else too — packaging, print, other platforms.

Every other QR type points somewhere online. Plain text is the one type that needs nothing hosted at all — the answer is inside the code itself.
