Every QR code hides a link, and you can't see where it goes until you open it. SeQRCode reads the code first and checks the link for phishing tricks, so you decide before you visit. HOW IT WORKS Point your camera at a QR code or barcode. SeQRCode shows what's inside and rates it Safe, Low, Medium or High risk, with a plain reason for every warning sign. Safe links open with one tap. Flagged links show the security check first, and high-risk links are blocked. 11 CHECKS ON EVERY LINK • Look-alike domains that imitate a well-known site • Look-alike letters swapped in to fool the eye • Link shorteners that hide the real destination • Raw IP addresses and unusual ports • Risky domain endings such as .top • Pressure words such as "verify", "confirm" or "expired" • Fake login pages and risky file downloads • Hidden script and data links • Cryptocurrency addresses, so you double-check before sending money ONE DIAL FOR EVERY CODE • QR: QR codes only, for the fastest lock • BAR: EAN-13, EAN-8, UPC-A, UPC-E, Code 39, Code 93, Code 128, ITF-14 and Codabar • ALL: everything above, plus Aztec, Data Matrix and PDF417 • A torch switch for dim menus, tickets and parking meters YOUR SCAN LOG • Every scan is saved on your phone with its time and risk rating • Filter safe and flagged scans, delete one scan or clear them all • Turn history off at any time in Setup PRIVATE BY DESIGN • Links are checked on your phone.
