How-to

Scan a QR code from a screenshot on iPhone, Android, or a computer. The camera and Live Text often fail. The free Qrblox tool reads the saved image and previews the link first.

How to put a circular QR (round QR code generator) on a printable freebie or coupon: size, quiet zone, contrast, and a claim URL at qrb.dev/f/{CODE} — not a tiny gray stamp.

Giver-side how-to: list a local freebie with a Qrblox freebie code. One QR per item opens qrb.dev/f/{CODE} in the browser. When a curb pile needs TAKEN — and when a paper note is enough.

Put one round QR on a sticker or photocard so the scan opens a Qrblox claim page (qrb.dev/f/{CODE}) with live N left — not your personal number or DMs.

Four QR mistakes that kill a freebie pack: too small, no quiet zone, retargetable tracking hops, and forcing an app install just to see the claim page. What to do instead with Qrblox.

Use the free Qrblox round QR code generator — the same circular QR code generator — then follow size, contrast, and quiet-zone rules so the round QR still scans.
