This QR can be photocopied. A FirstScanIt QR can't be faked.
A plain QR code is just a link — anyone can copy it onto a counterfeit. FirstScanIt issues cryptographically signed QR codes that prove a product is genuine, detect clones in real time, and tell you where, when, and how often each code is scanned.

Paste your link or text above, choose a size and colours, and your QR code updates instantly. Download it as a PNG for print or a scalable SVG for design files. There is no signup, no watermark, no expiry, and no limit on how many you generate. Everything runs in your browser, so your content is never sent to a server.
Which Error-Correction Level Should I Use?
QR codes include built-in redundancy so they still scan when partly damaged or dirty. Level L recovers ~7% and makes the smallest code; M (~15%) is the everyday standard; Q (~25%) and H (~30%) are best when the code will be printed small, on curved surfaces, or in tough environments such as pharmaceutical and industrial packaging.
Print Tips for Reliable Scanning
- Keep a clear "quiet zone" (white margin) around the code — at least 2 modules.
- Maintain strong contrast: a dark code on a light background scans best.
- Use the SVG download for print so the code stays sharp at any size.
- Don't scale below ~2 cm for packaging, and test-scan before mass printing.
Static vs. Secure QR Codes
A standard (static) QR code encodes a fixed link and offers no protection — if a counterfeiter photographs it, their fake scans exactly like the original. For brand protection you need a secure, signed QR where each code carries a tamper-proof cryptographic signature and a unique serial, so duplicate scans are flagged instantly. That is what FirstScanIt provides for pharmaceutical, FMCG, and high-value brands.

Questions and answers
Can a plain QR code show that my product is genuine?
No. Anyone can print a plain QR code that opens any page. For product authentication you need a code signed by the manufacturer, which is what FirstScanIt provides.
Do the codes expire?
No. The code holds your link or text directly, so it works as long as that link does.
Which error correction level should I pick?
Medium suits most print. Choose high if the code may get scratched or have a logo over it.
