Practical QR projects
Put an owner contact QR on a pet tag
Make a free static QR code for a pet tag by entering an owner phone number as text or a contact website URL. PrivQR encodes it locally without an account. Print the image or make an STL, then scan the finished tag. It is not a tracker and sends no scan notifications.
Create a pet contact QRMake it in three steps
- Choose the minimum useful contact information: an owner phone number with country code, or a stable contact page you control. Avoid publishing a home address.
- Create a PNG or SVG in the private QR generator, or use QR Code to STL for a printable model. Add a readable phone number beside the QR in your own layout.
- Attach one sample safely and scan the tag while it moves and curves against the collar. Confirm that a finder can read the contact details without signing in.
Make the tag useful to a stranger who finds your pet
Keep a readable phone number as a fallback
A finder may not have a working camera or connection. Put a visible contact number beside the QR using your own layout tool. For the QR payload, a short line such as “Owner: +1 202 555 0148” is plain text; PrivQR does not create an owner profile or promise a one-tap call interface.
Balance privacy against reachability
Anyone who sees the tag can scan its content. Local encoding protects the creation step, not information printed on a public tag. Choose a contact number or page you are comfortable sharing and leave medical records, access codes and private addresses out of the payload.
Check the collar-sized result
Small circular tags leave little room for a square QR and its clear border. Do not crop the corners to fit a decorative shape. Keep the payload brief and use a larger tag or a simpler readable label if the finished sample does not scan reliably.
Plan for wet surfaces and changed numbers
Scan after the tag is sealed or finished, because glare and surface wear change readability. If you encode a phone number directly, replacing that number means making a new tag. A contact page at your own stable URL can be updated, but you must keep that page available.
Free, with no account
PrivQR core QR generation is free and does not require an account or login. You arrange your own printing and any destination website. See the existing Free No-Login Access terms.
Questions before you make it
Will this pet QR tag show my pet’s location?
No. A PrivQR pet tag is a static contact label, not a GPS or Bluetooth tracker. PrivQR does not locate the pet or report where someone scans the code.
Will I get a notification when someone scans the tag?
No. PrivQR provides no scan notifications or scan statistics. A finder needs to contact you using the information you put in the code or on the tag.
Does PrivQR host a pet profile?
No. PrivQR creates the QR image or STL. If you use a website URL, you arrange that page yourself and check that a stranger can open it.
Can the contact QR expire?
PrivQR adds no expiry to the static code. A printed phone number can become outdated, a linked website can go offline, and a worn tag can stop scanning. Recheck the physical tag and contact details after changes.
