FAQ
Questions people ask before choosing
I have never printed a QR code. Where do I start?
Read how cards work for the four moving parts, then the dynamic code guide for what stays editable after printing. If all you need is one network or one contact, the Wi-Fi and vCard generators run inside this browser.
Do these guides require an account?
No. Every tool here generates in the browser. You only sign up when you want to edit a code you already printed, or restore a card you deleted.
Why does the site talk about cards instead of codes?
Because a code is a pointer and a card is an object with boundaries and a state. Printing a pointer is easy; getting something back from it is the part worth designing.
