A normal QR code is just a URL. QRalo adds an Ed25519 signature so a verifier can check issuer and integrity before redirect.
Every QRalo code is signed with Ed25519. If the payload is altered, verification fails.
Track codes from one dashboard. Expire or revoke anytime. Analytics on scans.
Anyone can check a code at qralo.com/scan or via the verify redirect — no app install required.

For large organizations
QRalo uses Ed25519 cryptographic signatures to prove QR code authenticity. You get real-time analytics, custom branding, instant revocation, and a centralized dashboard to manage all your QR codes.
No. You generate QR codes through our web dashboard, then print or display them anywhere. Standard camera apps can scan them like any QR code.
You can see scan counts, timestamps, locations, and device types. IP addresses are hashed for GDPR compliance, so individual users remain anonymous.
Each QRalo QR code contains a cryptographic signature that proves it was issued by your organization. Anyone can copy the visual QR code, but they cannot forge or modify the signature without your private key. The integrity is verifiable.
No product can. For QRalo-issued codes that people verify, a swapped non-signed sticker fails verification or is clearly not yours. Guests who scan random unsigned stickers with a normal camera and skip verification are not covered. Optional URL lists only catch already-known malicious destinations.
We offer a free Starter plan (3 active QR codes, 100 scans per QR code). Business plan is 9.99€/month with unlimited QR codes, unlimited scans, custom branding, and advanced analytics. Enterprise plans available on request.
Ed25519 signatures are only 64 bytes (vs 256 bytes for RSA-2048), perfect for QR codes where space is limited. It's also faster and just as secure.
Private keys are encrypted with AES-256-GCM using a unique salt and Scrypt key derivation. Even with database access, keys cannot be decrypted without the master encryption key.
Yes! From your dashboard, you can revoke any QR code immediately. Revoked QR codes will show as invalid when scanned and verified.
All QRalo QR codes redirect to our verification page which automatically checks the cryptographic signature. The QR code URL encodes the signature and destination—verification happens transparently before redirecting to the final URL.
Yes! Business and Enterprise plans include CSV and JSON export of all scan data, including timestamps, locations, and device information.
Any modification to a QRalo QR code will invalidate the cryptographic signature. The verification will fail, alerting users that the QR code has been tampered with.
Contact support immediately at security@qralo.com. We can revoke all affected QR codes and issue new cryptographic keys. Previously issued QR codes will become invalid.
We hash IP addresses and support data export/deletion requests. We store QR metadata, not the full content of destination pages. For HIPAA or other regulated use cases, consult your compliance officer — we do not claim sector-specific certification by default.
API access is on the roadmap for Business and Enterprise. Email contact@qralo.com if you need early access for an integration.
