As the EU Ecodesign for Sustainable Products Regulation (ESPR) comes into effect, businesses must decide how to deliver Digital Product Passport information to consumers, regulators, and recyclers. The two dominant technologies are QR codes and NFC (Near Field Communication) tags.
This guide provides a comprehensive comparison to help you make the right choice for your products, industry, and budget. We'll examine costs, technical capabilities, consumer adoption, regulatory requirements, and implementation strategies.
Quick Verdict
For most businesses, QR codes are the recommended choice for Digital Product Passports due to their lower cost, universal accessibility, and explicit compliance with EU ESPR requirements. NFC is preferred for luxury goods where authentication and premium experiences justify the higher cost.
Understanding the Technologies
What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that stores information in a pattern of black and white squares. Originally invented by Denso Wave in 1994 for automotive parts tracking, QR codes have become the most widely adopted scanning technology globally.
For Digital Product Passports, QR codes typically use the GS1 Digital Link standard, which encodes a URL that resolves to the product's passport data. This allows a single scan to access comprehensive product information.
QR Code Key Features
- Optical scanning via smartphone camera
- Data capacity up to 7,089 numeric or 4,296 alphanumeric characters
- Error correction up to 30% of data damage
- Scanning distance: 10cm to 10m depending on size
What is NFC?
NFC (Near Field Communication) is a wireless technology that enables data transfer between devices within close proximity (typically 1-4cm). NFC tags are small chips that can store data and transmit it when tapped with a compatible smartphone.
For Digital Product Passports, NFC tags store a URL or unique identifier that links to the product's passport data. They can also store additional authentication data for anti-counterfeiting purposes.
NFC Key Features
- Radio frequency communication (13.56 MHz)
- Data capacity: 48 bytes to 8KB (depending on tag type)
- Unique ID for anti-counterfeiting
- Scanning distance: 1-4cm (requires physical proximity)

| Anti-Counterfeiting | Limited (can be copied) | Strong (unique ID) |
| Works When Dirty | 30% damage tolerance | Works through materials |
| ESPR Compliant | ✓ Explicitly mentioned | ✓ Accepted |
| Durability | Depends on printing | 10+ years lifespan |
| Best For | Mass market products | Luxury & authentication |
Consumer Accessibility
QR codes have a significant advantage in consumer accessibility. According to Statista's 2024 Global Consumer Survey, 89% of smartphone users have scanned a QR code, with 74% using their native camera app. In contrast, only 45% of consumers are familiar with NFC scanning, despite most modern smartphones supporting it natively.
This accessibility gap matters for Digital Product Passports, where the goal is to make product information available to all stakeholders including consumers, recyclers, and regulators.
Durability and Environment
NFC tags are more durable in challenging environments. They work when covered by dirt, paint, or fabric, and maintain functionality for 10+ years. QR codes, being optical, require visibility and can be damaged by scratches, fading, or contamination. However, high-quality printing techniques (UV-resistant inks, lamination) can significantly extend QR code lifespan.
EU ESPR Requirements
The EU Ecodesign for Sustainable Products Regulation (ESPR) specifies requirements for Digital Product Passport data carriers. Understanding these requirements is essential for compliance.
ESPR Data Carrier Requirements
- 1ISO/IEC Compliance: Must comply with ISO/IEC 15459 or ISO/IEC 18004 (QR code standard)
- 2Physical Placement: Must be affixed to the product, packaging, or accompanying documentation
- 3URL Resolution: Must resolve to the product's passport data in a machine-readable format
- 4Durability: Must remain readable throughout the product's expected lifetime
GS1 Digital Link Standard
The EU recommends using the GS1 Digital Link standard for QR codes in Digital Product Passports. This standard creates a single code that:
- Encodes the GTIN (Global Trade Item Number) in a URL format
- Resolves to the appropriate content based on the scanner (consumer vs. retailer)
- Supports multiple data types through a single scan
- Provides backward compatibility with traditional barcode systems
Both QR codes and NFC tags are ESPR compliant, but QR codes are explicitly mentioned in the regulation text and are the expected default for most product categories.
Industry-Specific Recommendations
Different industries have different requirements based on product value, counterfeiting risk, environmental conditions, and consumer expectations. Here are our recommendations:
Fashion & Textiles
Recommendation: QR Code (NFC for luxury segment)
Mass market fashion should use QR codes for cost-effectiveness. Luxury brands benefit from NFC for authentication and premium unboxing experiences. Care labels can accommodate both.
Electronics & Batteries
Recommendation: QR Code
QR codes are practical for electronics due to standardized packaging and the need for regulatory information (including Battery Passport requirements). Durability is less of a concern as products have defined lifespans.
Furniture & Construction
Recommendation: QR Code (durable materials)
Use laser-etched or metal-plate QR codes for durability. Products often have 10-50 year lifespans, so durability is critical. NFC tags may be hidden inside products for long-term access.
Luxury Goods & Watches
Recommendation: Hybrid (QR + NFC)
Luxury goods justify the higher cost of NFC for authentication and premium brand experiences. A hybrid approach with both QR and NFC provides maximum flexibility and security.
Cosmetics & Personal Care
Recommendation: QR Code
QR codes are ideal for cosmetics due to limited packaging space and relatively short product lifespans. Integration with ingredient transparency and usage instructions adds consumer value.
