KavachScan: QR Scam Check

Abhijeet Verma

About this app

Every QR scanner opens the code. KavachScan checks it first.

Fake UPI stickers on shop counters and parking walls. "Scan to receive money" tricks. Shortened links hiding phishing pages. QR fraud is exploding — and the scanner built into your camera opens everything instantly.

KavachScan is your kavach — a safety shield between the QR code and your phone. Nothing opens without your approval.

UPI PAYMENT PROTECTION
Reads UPI and Bharat QR (plus PayNow, SGQR, QRIS, PromptPay, Pix and other national payment QRs). Shows who you would actually pay — the real account, not just the display name — and how much. Flags a personal account posing as a big brand. And it reminds you: receiving money never requires scanning a QR or entering your UPI PIN.

Verified payments hand off to YOUR own payment app, where you approve as usual. KavachScan never touches the money.

WHAT THIS CODE DOES — IN PLAIN LANGUAGE
Every scan gets a one-paragraph explanation anyone can understand: who you'd pay, which Wi-Fi you'd join, where a link really leads — before you act. Tap the speaker to hear the verdict read aloud.

SCAM CHECKS ON EVERY SCAN
• Reveals the true destination behind shortened links without opening the page
• Flags lookalike domains, brand impersonation, hidden credentials, raw-IP servers
• Matches every link against live phishing and malware databases, updated automatically
• Blocks code-executing link types outright
• Warns on premium SMS, rogue Wi-Fi, crypto address swaps, and 2FA hijack codes

EVIDENCE WHEN YOU NEED IT
Scammers peel their fake stickers off after the fraud. When KavachScan detects a code, it saves a photo of the code and its surroundings on your phone only — so if something goes wrong you can generate a printable incident report (A4 PDF) with the full code contents, timestamps and the photo, ready for your bank or the police. You choose how long evidence is kept: 7, 30 or 60 days.

PRODUCT BARCODES TOO
Scan any grocery barcode for instant product info: brand, Nutri-Score, processing level, allergens.

PRIVATE BY DESIGN
No accounts. No ads. No analytics. We run no server, so we never see what you scan — your history stays on your phone and you can wipe it in one tap.

Two checks do reach the internet, from your phone and never to us: following a shortened link to find its real destination (the same request your browser would make, without opening the page), and looking up a product barcode. Everything else — every safety check — runs entirely on your device.

Aapka QR kavach. Scan first, open later.
