What Are QR Codes?

QR codes, short for Quick Response codes, are two-dimensional barcodes that store information in a pattern of black squares arranged on a white background. Originally developed in Japan in 1994 by Denso Wave, they have gained widespread popularity due to their ability to store large amounts of data compared to traditional barcodes. The codes can contain various types of information, including URLs, text, contact information, and multimedia files.

QR Codes in Anti-Counterfeiting

Innovations in QR codes have advanced the anti-counterfeiting movement significantly. When combined with non-clonable encryption, QR codes provide a verification layer that leaves no viable path for duplication. The uniqueness and non-cloneability factor offered by advanced QR labels gives brands a decisive advantage in preventing counterfeiting.

The codes are scanned using a smartphone or a QR code reader, which interprets the pattern and retrieves the stored data. They have found applications in various industries, including marketing, transportation, healthcare, and ticketing. These labels are particularly used for anti-counterfeiting in major industries.

Applications

1
Product Authentication
Each product unit is assigned a unique QR code linked to a cloud record. Scanning the code confirms whether the item is genuine and untampered.
2
Supply Chain Traceability
QR codes can be linked to unique identifiers to track a product's movement through the supply chain, from manufacturing to retail, improving efficiency and preventing counterfeiting.
3
Consumer Engagement
Brands use QR codes on packaging to direct consumers to loyalty programmes, warranty registration, product information, and reorder portals.
4
Marketing and Campaigns
QR codes on printed materials, packaging, and outdoor media connect physical touchpoints to digital content, enabling measurable campaign performance tracking.

Frequently Asked Questions

Yes, QR codes can be scanned using camera applications on most smartphones. Many phones have built-in readers accessible through the camera app. Some advanced non-clonable codes may require a specific, custom-branded application to read the encrypted layer.

Normally, standard QR codes can be copied. Although it may not be simple, the possibilities are high. That is why advanced non-clonable 2D codes are being widely implemented across industries to fight counterfeiting and tampering. These codes carry encrypted server-side validation that detects duplicates even when the visual code appears identical.

Yes. QR codes can be linked to unique identifiers that track a product's movement through the supply chain, from manufacturing to retail. This helps businesses improve efficiency, prevent counterfeiting, and maintain accurate distribution records.

A standard QR code is a static pattern that can be photographed and reprinted exactly. A non-clonable QR code contains an encrypted layer tied to a specific product unit and verified server-side. Even if the visual code is copied, the server detects the duplicate scan and flags the product as suspicious.
