What is a text QR code?
A text QR code holds characters and nothing else. No scheme, no prefix, no instruction - the scanner reads it and shows the text. Because nothing is opened, dialled or connected, it is the safest kind of code to hand to a stranger and the right one whenever a machine, not a browser, is the reader.
Where plain text is the correct choice
- Serial and batch numbers on equipment, so a warehouse scanner reads what a human would type.
- Asset and inventory labels: an internal ID that means something only inside your own system.
- Machine and maintenance data: model, installation date, filter type - readable without a database.
- Short notes: a shelf reference, a recipe step, a locker code, a note in a museum display.
Limits worth knowing
A QR code stores a few thousand characters at most, and the more it stores the denser it gets. This generator accepts up to 1200 characters, which is well inside what stays readable at a sensible print size. If you need more, encode a reference and keep the long text where it belongs, in a system that can be updated.
Line breaks are removed on purpose: they end several payload formats early and are a common source of codes that scan differently on different phones. If you need a multi-line contact record, use the vCard page instead.
