A plain-text QR code stores text itself, not a link — so scanning it simply displays the message. It is perfect for instructions, serial numbers, product codes, secret messages, competition entries or a note that works with no internet at all.
Type your text, style the code and download a PNG or SVG. Because the content lives inside the code, it works completely offline and forever, with no account.
