Secure QR code generator
Secure QR codes with cryptographic signatures
Standard QR codes can be swapped or forged. QRalo signs every code with Ed25519 so scanners can prove who issued it, whether it is still valid, and whether it was tampered with — before the destination opens.
Signed at creation
Every QR payload includes an Ed25519 signature tied to your organization.
Verified before click
Users see issuer, status, and warnings before opening the destination URL.
Revoke anytime
Compromised or outdated codes become invalid instantly across scans.
Why “secure QR code” means more than a password on a link
Most QR generators only encode a URL. Anyone can print a lookalike sticker that sends guests to a phishing page. A secure QR code from QRalo carries a cryptographic proof of authenticity that cannot be forged without your private key.
That matters for high-risk surfaces: restaurant menus, parking payment posts, delivery notices, event check-in, and invoice QR codes — the exact places attackers overlay stickers.
