ScanShield: QR Scanner

Duo Aims

About this app

ScanShield: QR Scanner is a fast, privacy-first QR code and barcode scanner built for everyday use — without accounts, ads tracking your scans, or sending your data to the cloud.

Scan QR codes and barcodes instantly with your camera. Read URLs, Wi‑Fi networks, contacts, phone numbers, email, SMS, locations, payment links, and product barcodes (EAN, UPC, Code 128, and more). Everything stays on your device.

WHY SCANSHIELD?

• Offline-first — scan and review codes without needing an account
• Private by design — scan history and created QR codes stored locally on your phone
• Fast camera scanner — point, scan, and act in one tap
• Smart results — see what a code contains before you open a link or connect to Wi‑Fi
• Trust hints — offline checks help you spot suspicious links before you tap

SCAN ANYTHING

• QR codes — websites, text, Wi‑Fi, vCard contacts, calendar events, WhatsApp, UPI/payment, social profiles, maps
• Barcodes — retail product codes, Code 39/93/128, Data Matrix, PDF417, Aztec, ITF, Codabar, and more
• Gallery import — scan QR or barcode images already saved on your phone
• Batch mode — scan multiple codes in one session and save them to a collection
• Torch & flip camera — works in low light and on front/back camera

ACT ON SCANS
