QR Codes: From Innovation to Hidden Scams – How Arjuna Protects You
The Origin of QR Codes
QR codes (Quick Response codes) were first invented in 1994 by Denso Wave, a Japanese company, to track automotive parts in manufacturing. Unlike traditional barcodes, QR codes could hold much more information and could be scanned instantly with a simple device. Over time, their speed, flexibility, and ease of use made them popular far beyond factories.
What started as a tool for efficiency in manufacturing has today become a global standard for information sharing, payments, and marketing.
Where QR Codes Are Used Today
Over the last two decades, QR codes have become an integral part of everyday life. They are now used across multiple industries:
Marketing & Advertising – Brands place QR codes on billboards, posters, or product packaging to redirect customers to websites, offers, or campaigns.
Retail & Restaurants – From scanning menus at a café to redeeming discounts at a store, QR codes make shopping and dining seamless.
Payments & Banking – In India especially, QR codes have revolutionized UPI payments, allowing instant transactions without cards or cash.
Logistics & Manufacturing – Used to track inventory, parcels, and even supply chain details.
Ticketing & Events – Concerts, flights, and cinema tickets now commonly use QR codes as digital passes.
Healthcare & Education – Accessing reports, checking medicine authenticity, or learning modules are often powered by QR scans.
Simply put, QR codes are everywhere. They are fast, contactless, and widely trusted.
The Rapid Growth of QR Codes
The rise of smartphones and internet adoption has supercharged the growth of QR codes.
In India, the adoption of UPI and digital payments during and after COVID-19 made QR codes a household term.
Restaurants switched from paper menus to digital menus via QR for safety.
Retailers embraced QR for discounts and loyalty programs.
Businesses found them cost-effective since printing a QR on a poster or receipt costs almost nothing.
Reports suggest that billions of QR transactions now happen every year in India alone. From Tier-1 cities to rural markets, QR codes have become the face of the digital revolution in Bharat.
The Dark Side of QR Codes – QR Scams
But like every technology, what is meant for good is also exploited by scammers.
Here’s the problem: a QR code is just a sticker. To the naked eye, all QR codes look the same — a black-and-white square pattern. You can’t tell if it’s genuine or malicious until you scan it. And that’s exactly what cybercriminals exploit.
Common QR Code Scam Examples:
Restaurant Menu QR Scams
Imagine sitting at a restaurant table. You scan a QR code to view the menu — but instead of the menu, it redirects you to a fake payment page asking for card details or UPI login.
Some scammers even place fake QR stickers over genuine ones on tables, luring customers into entering payment details.UPI Payment Fraud
Fraudsters print malicious QR codes for payments, which when scanned either withdraw money automatically or redirect to fake apps. Many unsuspecting people lose thousands of rupees thinking they are making a genuine transaction.Public Poster & Event Scams
Fraudsters paste QR stickers on advertisements, posters, or tickets. Once scanned, they lead users to phishing sites that steal credentials.Phishing through QR Links
Some QR codes directly embed malware links that compromise your device once opened.
Why QR Scams Are So Dangerous
Invisible Risk: To the naked eye, a genuine QR and a malicious QR look identical.
High Trust Factor: People scan without thinking, especially in trusted environments like restaurants, banks, or shops.
Ease of Exploitation: Scammers only need to paste a new sticker — it’s cheap, simple, and effective.
Targeting the Common Man: Most victims are everyday users who don’t understand the hidden risks.
In short, what was designed for convenience has become an easy weapon for cyber fraud.
