QR code reader and generator focused on the Mexican market. No ads, no tracking, no subscriptions.

QRMex respects your privacy: it only asks for camera permission, collects no data, requires no account, and sends nothing to external servers. Everything you scan stays on your device.

⚡ KEY FEATURES

📷 QR and barcode scanning
• Live camera with fast detection.
• Supports multiple formats: QR, EAN-13/8, UPC-A/E, Code 39/128, PDF417, Aztec, DataMatrix.
• Scan from gallery: decode QRs in screenshots or images received via messaging.

🧾 Mexican SAT invoice (CFDI) verification
• Parses the QR of your Mexican invoice and shows UUID, issuer RFC, recipient RFC, and total.
• Opens the official SAT verifier with fields auto-filled.
• Warns you if the QR is incomplete (an issuer-side problem, not the app's).

🔒 Safe URL preview
• Before opening any URL, shows you the real domain.
• Detects shortened links (bit.ly, t.co, etc.), IP addresses instead of domains, deceptive characters (punycode), and other suspicious patterns.
• You decide whether to open.

📶 Wi-Fi codes
• Reads standard Wi-Fi QRs (WIFI:T:WPA;S:Network;P:password;;).
• Also interprets non-standard formats from Mexican routers: Telmex Infinitum, IZZI, Megacable, Totalplay, BBVA-WIFI, AT&T, Telcel.
• "Connect to this network" button: copies the password and opens system Wi-Fi settings.

• No analytics or telemetry.

📜 PERMISSIONS

QRMex requests only:
• Camera — to scan codes live.
• Photos — only when you tap "From gallery" to scan a screenshot.

That's it. If you're tired of QR apps that demand a dozen permissions, this isn't one.

🇲🇽 BUILT FOR MEXICO

International QR apps don't correctly parse Mexican SAT invoice QRs or non-standard router Wi-Fi codes. QRMex does.
