Serialised QR codes are having a moment. Interest has jumped significantly in our 2026 Global Connected Packaging Survey, with 73.2% of respondents scoring 4 or 5 out of 5 for interest in serialised QR codes for personalised engagement and fraud prevention — a 7.1 point increase from 2025. Authentication and anti-counterfeit has simultaneously emerged as the #1 driver for connected packaging adoption at 52.1%.
The timing is not coincidental. As the connected packaging market matures, brands are moving beyond the basics and serialisation is where the most sophisticated smart packaging players are heading.
What Serialised QR Codes Actually Are and How They Differ From Standard QR Code Packaging
A standard QR code is static. Every pack in a print run carries an identical code that takes every scanner to the same destination. It’s functional, scalable, and works well for many connected packaging applications.
A serialised QR code is different. Each individual pack carries a unique code, its own digital identity. Where a standard QR code is like a street address that directs everyone to the same front door, a serialised QR code is like a unique passport number. Every unit is individually identifiable, and every scan generates a unique data point. This distinction unlocks capabilities simply not possible with standard QR code packaging.
Serialised QR Codes for Anti-Counterfeit and Brand Protection
The most urgent application of serialised QR codes for many brands is authentication. When every pack has a unique identity, counterfeiting becomes dramatically harder. A genuine product can be verified at the point of scan, if the code has already been scanned in a different location or an implausible number of times, that’s an immediate red flag identifiable in real time.
For brands operating across multiple markets or selling products vulnerable to grey market diversion, serialisation provides supply chain visibility that was previously only achievable through expensive track-and-trace systems. The data generated by serialised QR scans, where products are being scanned, by whom, how often, builds a real-time picture of where genuine products are and where anomalies are occurring.
Personalisation at Scale Through Smart Packaging
The second major capability unlocked by serialisation is personalised consumer engagement. When every pack has a unique code, the interactive packaging experience delivered to each consumer can be tailored — by geography, purchase history, the specific product variant scanned, or data captured in previous interactions.
This is the connected packaging equivalent of addressable media. Rather than every consumer who scans a pack getting the same experience, brands can deliver genuinely personalised content — a loyalty reward calibrated to purchase frequency, a recipe recommendation based on previously scanned products, a sustainability message tailored to the consumer’s location.
Supply Chain Intelligence From Serialised QR Code Packaging
Beyond consumer-facing applications, serialised QR codes generate supply chain intelligence with significant operational value. Brands can track product movement through the supply chain with granular precision, identifying bottlenecks, monitoring cold chain compliance, managing product recalls with precision rather than blunt-force category withdrawal.
The 2027 GS1 transition to QR codes at retail is accelerating interest in serialisation. GS1 Digital Link QR codes can carry serialised data as well as the standard product identifier, meaning the same code that satisfies a retailer’s point-of-sale scanning requirement can also carry unique serial number data for supply chain tracking and consumer-facing authentication.
