Do the QR codes expire?

No. The data is encoded directly into the image, so a downloaded QR code works forever — there is no tracking link that can expire.

What is error correction in a QR code?

Error correction lets a QR code still scan when partly damaged or obscured. Higher levels (Q, H) tolerate more damage but make the code denser.

Can I add colors or a logo?

You can set custom foreground and background colors. Keep strong contrast so scanners read the code reliably.
