NFC vs QR Code for the Digital Product Passport: Which One Should Your Brand Choose?
The ESPR Regulation (Ecodesign for Sustainable Products Regulation) requires that many categories of products placed on the European market include a Digital Product Passport (DPP) accessible through a physical data carrier.
The regulation defines which information must be made available, but it does not mandate a specific technology. The choice between QR codes, NFC, or a hybrid approach remains up to the brand. This decision is not purely technical: it affects production costs, consumer experience, anti-counterfeiting capabilities, and supply chain scalability.
In this guide, we compare QR codes and NFC for the Digital Product Passport across every relevant dimension, including technical characteristics and practical recommendations. Within the Digital Product Passport (DPP) ecosystem, the data carrier is the physical element that connects the product to its digital identity; the two technologies most commonly used today are QR codes and NFC tags.
How QR Codes Work for the DPP
A QR code (Quick Response code, ISO/IEC 18004 standard) is a two-dimensional barcode that encodes data in a matrix of black and white modules. In the context of the Digital Product Passport, the QR code typically contains a URL that directs the user to the product's digital record.
Static vs Dynamic QR Codes
A static QR code directly encodes the destination URL within the matrix. Once printed, the URL cannot be modified. This approach is simple but rigid: if the URL changes, the QR code becomes unusable.
A dynamic QR code, instead, encodes a redirect URL managed by a platform such as AUTHENTICA. This allows the brand to update the destination, the information displayed, and the analytics without reprinting the code. For the Digital Product Passport, dynamic QR codes are generally the preferred option because they allow compliance data to be updated over time.
GS1 Digital Link and Interoperability
The GS1 Digital Link framework allows a GS1 identifier, such as a GTIN, to be encoded directly within the QR code URL. This enables interoperability with existing supply chain systems: the same QR code can be scanned both by industrial scanners along the logistics chain and by smartphones at the point of sale.
Example of a GS1 Digital Link structure: https://id.authentica.id/01/08001234567893/21/ABC123 — here 01 represents the GTIN and 21 the serial number. When the URL is resolved, it returns the complete Digital Product Passport, either in human-readable format or in a structured format such as JSON-LD.
Advantages of QR Codes for the DPP
- Minimal marginal cost — QR codes are printed directly on labels, packaging, or hangtags with no electronic components required.
- Universal accessibility — Any smartphone with a camera can scan a QR code without requiring a dedicated app.
- Fast integration — QR codes do not require changes to existing production lines.
- High scalability — They are well suited for high-volume production where simplicity and compatibility are essential.
Limitations of QR Codes
- No intrinsic security — A QR code can easily be photographed and reproduced.
- Physical degradation — Scratches, abrasion, or environmental exposure may reduce readability.
- Risk of replacement — A fraudulent QR code can potentially be placed over the original one.
How NFC Tags Work for the DPP
NFC (Near Field Communication, ISO/IEC 14443 and ISO/IEC 18092 standards) is a short-range wireless technology. An NFC tag consists of a microchip with an integrated antenna that communicates with smartphones via an electromagnetic field, without requiring a battery.
NTAG 424 DNA and SUN Authentication
For Digital Product Passport implementations that require anti-counterfeiting capabilities, one of the most advanced chips available is NXP NTAG 424 DNA, which supports the SUN (Secure Unique NFC) protocol. This protocol generates a unique cryptographic signature every time the tag is read.
How SUN Authentication Works
Each tap generates a MAC (Message Authentication Code) based on an AES-128 key stored in the chip and an incremental counter. The transmitted URL includes the MAC and the counter as parameters: https://id.authentica.id/t/ABC123?e=0400...&c=000042. The server verifies the MAC and checks that the counter has not been used previously; if the parameters are invalid, the system flags a potential counterfeiting attempt. This mechanism makes cloning the tag extremely difficult.
Advantages of NFC for the DPP
- Cryptographic authentication — Each read generates a unique signature verified by the server.
- Physical resistance — Tags can be encapsulated in protective materials and withstand washing, pressure, and demanding environmental conditions.
- Tamper detection — Some tags are designed to break or deactivate if removed from the product.
- Premium user experience — The tap interaction is fast and intuitive.
- Invisible integration — The tag can be embedded directly inside the product with no visual impact.
Authentica implements NTAG 424 DNA with full SUN (Secure Unique NFC) authentication. Every tag generates a one-time cryptographic signature on each tap, making physical counterfeiting virtually impossible, even with sophisticated cloning equipment. See our NFC implementation →
Comparison Table: NFC vs QR Code for the DPP

| Device compatibility | Almost universal | High |
| Data capacity | High | Sufficient for URL |
| Tamper detection | No | Yes |

When to Choose QR Codes
QR codes are ideal when:
- the product has a relatively low unit value
- the packaging is disposable
- maximum smartphone compatibility is required
- the Digital Product Passport is used mainly for regulatory compliance
- scalability across large production volumes is the priority
When to Choose NFC
NFC technology is preferable when:
- the product belongs to the luxury or premium fashion segment
- anti-counterfeiting protection is a priority
- the product has a long lifecycle
- the brand wants to enable resale or circularity services
- a premium user experience is part of the brand positioning
The Hybrid Approach: QR + NFC
Many premium brands combine both technologies. The QR code on the packaging guarantees universal accessibility and compatibility with supply chain systems; the NFC tag embedded in the product enables cryptographic authentication and a more advanced customer experience. With a platform such as AUTHENTICA, both carriers point to the same digital product identity.
ESPR Compliance: What the Regulation Requires
The EU ESPR Regulation requires that every covered product include a unique identifier accessible through a compliant data carrier. For EU compliance and deadlines, see the DPP timeline. The main requirements include:
- compliance with ISO/IEC standards
- access to a URL containing Digital Product Passport information
- free consumer access
- adequate durability of the data carrier
Both QR codes and NFC meet these requirements.
Frequently Asked Questions
What is the main difference between NFC and QR codes for the DPP?
A QR code is a printable optical carrier readable with any camera. An NFC tag is an electronic chip that requires close proximity and enables cryptographic authentication.
Can NFC and QR codes be used together?
Yes. The hybrid approach is increasingly common because it combines universal accessibility with secure authentication.
How should a brand choose between NFC and QR codes?
The choice depends on product value, required security level, desired user experience, and supply chain integration.
Does the ESPR regulation mandate a specific technology?
No. The regulation only requires that the data carrier comply with ISO/IEC standards.
Where should brands start?
Implementation depends on the product and supply chain. Many brands start with a pilot project to evaluate which technology best integrates into their production process.
