Use case
Sticker QR code fraud
What to do when public QR codes may have been covered by fraudulent stickers.
Benefit
Inspect edges and layering around the code.
Benefit
Compare the domain with the official brand or location.
Benefit
Avoid payment pages that feel unexpected.
Privacy
Local-first by design
SafeCodeScan reads the code locally; it cannot verify the physical sign owner.
Why stickers matter
A printed sign can be legitimate while the QR code on top has been replaced. This is relevant for parking meters, restaurant tables, chargers, delivery notices and event posters.
Physical inspection
Look for raised edges, different paper texture, crooked placement or a code that covers another printed code. If something looks layered, use extra caution.
Digital inspection
After scanning, compare the domain with the official website. Payment or login prompts from a surprising domain should be treated as suspicious.
Method
How the check works
SafeCodeScan decodes the payload locally, separates readable parts such as protocol, host, path and parameters, then explains common warning signs in plain language.
Limits
No result is a guarantee
A code can change behavior after you open a destination. Always verify the source, the displayed domain and the context before entering data or making payments.
Does this send data to a server?
SafeCodeScan reads the code locally; it cannot verify the physical sign owner.
Is the result guaranteed?
No. SafeCodeScan gives cautious hints and local checks, not a guarantee.
Can I use it on mobile?
Yes. The interface is mobile-first and supports camera or local generator workflows.
