A QR code on a shop window, menu or business card saves people from typing a long address. A bad one is worse than none, because nobody can scan it and nobody tells you.
Know what you are encoding
A link, a phone number, a Wi-Fi password and plain text all work. Shorter content makes a simpler code, and simpler codes scan faster from further away.
Size and contrast
Print it at least 2 cm wide on a card, and bigger on posters. A dark code on a light background works best, and never put the code on top of a busy photo.
Always test it
Scan the final printed version with two different phones before you order a hundred copies. Fix any problem while it is still cheap.
Free, no signup, and your files never leave your device.

Do QR codes expire?
A code made from a plain link does not expire. It only stops working if the page it points to disappears.
Can I put a logo in the middle?
It is possible, but it makes scanning less reliable, so test carefully or leave it out.
