Creator & shop how-to
Hide a freebie in a QR code
List the item, mint a round QR, print it on the object, and track remaining on the claim page. Built for “hide freebie in QR code” and “QR code for giveaway” — without a mystery-prize form.
Short answer
Point the QR at https://qrb.dev/f/{CODE}, not at your DMs. Scanners open the claim page in a browser. No app needed to view. No payment info. Qrblox is the key that minted the page.
List → mint → print → track
Four verbs. One printed mark.
1. List or mint
Download Qrblox or open app.qrblox.com. List the freebie or mint a pack. Copy the claim URL.
2. Round QR
Paste that URL into the round QR code generator. Download a high-contrast PNG. Do not shrink it to fit leftover space.
3. Print & track
Print one QR per pack or item. After launch, watch remaining / TAKEN on the claim page — edit the page, keep the ink.
List the freebie or mint a pack
The giver is you. Qrblox records the listing and issues the claim URL. Use the iOS app or app.qrblox.com. One pack (or one scarce item) gets one code. Twenty photocards that all open your bio are not a claim system — they are twenty people in the same inbox.
Mint a round QR
Open the round QR code generator. Paste the claim URL. Keep high contrast and a quiet zone. Download the PNG. A circular mark sits on a lid, sticker, or photocard without square corners fighting the die-cut.
“Circular QR code” and “round QR code” are the same generator. Aliases such as /circular-qr-code-generator already redirect here so you do not maintain two tools.
Print it on the object
Size beats cleverness. A code that does not scan is not a giveaway. Keep it large enough for a kitchen-table camera, on a flat face, with a light quiet zone. Details: QR mistakes that kill free packaging and printable coupons.
Track remaining — do not retarget the hop
After print, the QR should keep opening the same claim page. If the note, playlist, or count changes, edit the page. A retargetable tracking hop on a printed pack is how a giveaway turns into a surprise URL six months later.
Trust and abuse notes — private claim pages, no payment forms, no public code gallery — are on how claim codes work.
Object-specific writeups
Giveaway QR — questions
How do I hide a freebie in a QR code?
List the freebie or mint a pack in Qrblox, copy the qrb.dev/f/{CODE} URL, make a round QR that points at that URL, print it on the object, and watch remaining / TAKEN on the claim page. Scanners do not need the app to view the page.
What QR code should I use for a giveaway?
Use a QR that opens the claim page in a browser — not a personal number, not a DM prompt, and not a retargetable ad hop. A round QR sits cleanly on stickers, lids, and photocards. Generate one free at /round-qr-code-generator.
Do people need to download an app to claim?
They need a camera and a browser to see the claim page. No payment info. Download Qrblox if you are the giver listing or minting — not as a wall in front of the gift.
How do I track how many freebies are left?
The claim page shows a live remaining count and flips to TAKEN. Edit that page when inventory changes. Keep the same printed QR on every copy in that pack.
Make the mark. Keep the same printed QR.
Edit the claim page when the copy changes. Qrblox is the key, never the gift.
