Questions about qr code generator
What sizes of QR code still scan?
As long as the finished code is printed at least 2 cm across and the content is short, every mainstream scanner reads it. Keep the contrast high and leave the quiet zone around the code intact.
What is error correction and which level should I use?
Error correction adds redundancy so the code still scans when part of it is damaged. Low survives about 7 percent damage, Medium 15 percent, Quartile 25 percent and High 30 percent. Medium is a good default.
Does the code work for Wi-Fi and contact details?
Yes. Standard QR codes can carry a Wi-Fi login, a vCard, a geo location or a plain message, and most phones switch to the right action when they scan it.
