NTAG 223/224 DNA for Pharmaceutical Packaging Authentication and Anti-Counterfeiting

NTAG 223 DNA and NTAG 224 DNA are security-focused NFC integrated circuits that can add cryptographic tag authentication to a pharmaceutical packaging workflow. When built into a suitable NFC label or inlay and connected to a correctly configured verification service, they allow a medicine pack to present dynamic authentication data for checking. This gives pharmaceutical brands and packaging solution providers an additional digital identity layer beyond a static printed code.

The chip is only one part of the solution. Packaging design, individual product identification, secure personalization, cryptographic key management, backend verification and market-specific regulatory controls must be planned together. For custom anti-counterfeit NFC label options, seeKaisere's anti-counterfeit NFC tags.

Why Add NFC Authentication to Pharmaceutical Packaging?

Medicine packaging can carry several types of information, including product identity, batch or lot details, expiry information and instructions. A conventional printed code can direct a user to information, but a static code by itself does not prove that the code was issued for a genuine individual package. A copied image can be reproduced on another item.

A secure NFC design can add a cryptographic check to the interaction. NTAG 223/224 DNA supports Secure Unique NFC (SUN) message authentication protected with AES-128. In a configured system, a compatible reader or NFC-enabled smartphone reads the tag's dynamic message and sends the required data to a verification service. The service checks the message according to the project's cryptographic and product-record rules before displaying a result.

This approach supports brand protection and product identification workflows, enabling the verification of individual pharmaceutical items, the confirmation of package contents, or the authentication of the product as a whole. This functionality can be achieved as long as NFC technology is integrated into the physical structure and design of the pharmaceutical packaging.Authentication results also depend on correct personalization, key protection, backend rules and operational controls.

How Does NTAG 223/224 DNA Pharmaceutical Packaging Authentication Work?

A practical project normally combines an NFC IC, an antenna and label construction, product-level data, a verification service and a user-facing result. The exact architecture should be agreed by the pharmaceutical brand, solution integrator and label supplier before samples are approved.

1. Assign a product identity. Define how each saleable pack will be identified. The business system may associate a unique item record with a product code, batch or lot number, expiry date and other approved attributes. Decide which information belongs in the tag and which information remains in a controlled database.

2. Select the IC and label construction. Choose NTAG 223 DNA or NTAG 224 DNA according to the security requirements and memory needs. Confirm the antenna geometry, label size, substrate, adhesive, printing and attachment point for the actual carton, bottle, cap or other pack.

3. Personalize and encode securely. Define the NDEF structure, URL or identifier format, authentication configuration and the party responsible for key provisioning. Security-sensitive key material should be handled through an agreed controlled process, not sent in an ordinary RFQ or artwork file.

4. Read the tag. A compatible NFC-enabled smartphone or reader taps the package and reads the configured NFC message. The exact experience depends on device support, operating system behavior, tag configuration and the selected application or web flow.

5. Verify the dynamic message. The verification service checks the authentication data and associates the result with the relevant product record. The business rules may also assess repeated, unexpected or otherwise suspicious scans.

6. Return an appropriate result. The user may be directed to approved product information or a verification status. The brand should define the meaning of each status and what a user should do when authentication fails or cannot be completed.

Where Can NFC Security Labels Be Integrated on Medicine Packs?

Folding cartons and medicine boxes

An NFC label may be placed on a carton panel or across an opening flap, depending on the required tap position and whether the project also needs visible evidence of opening. The design team should check folds, varnishes, coatings, print coverage, nearby foil layers and the available space for the antenna. If the label is intended to show removal or opening, that behavior comes from the label and carton construction, not from the standard NTAG 223/224 DNA IC alone.

Medicine bottles and caps

Labels for bottles, vial cartons or caps need to be evaluated against curvature, surface energy, adhesive performance, moisture exposure and the distance between the antenna and liquids or metal components. A label that reads reliably on a flat desktop sample may behave differently after it is applied to a filled container. Test the final package, not only the loose inlay.

Seals and tamper-evident closures

Where first-opening evidence is important, the NFC inlay can be considered as part of a tamper-evident label or seal. Destructible materials, split constructions or visible VOID patterns may be evaluated as separate physical security features. Their effectiveness depends on the chosen material, die-cut, adhesive, application process and package surface.

Blister packs and foil-based packaging

Blister structures and foil-based components require particular attention because metal layers can affect NFC antenna coupling. Confirm whether the tag is placed on an outer carton, leaflet, label or another suitable location. Antenna tuning and smartphone readability must be verified on production-representative samples.

NTAG 223 DNA vs. NTAG 224 DNA for Pharmaceutical Packaging

Both ICs support AES-128-protected SUN message authentication. The main selection differences are user memory and the method available for protected memory access. Choose according to the system's security architecture rather than assuming that the larger memory option is automatically better for every medicine pack.

When to consider NTAG 223 DNA: when 144 bytes of user memory and 32-bit password protection for memory access meet the defined application requirements.

When to consider NTAG 224 DNA: when the project needs 208 bytes of user memory or AES-128-based three-pass mutual authentication to protect access to configured memory areas.

Both options can support SUN dynamic message authentication. The 224 DNA's mutual authentication is a separate protected-memory-access function; it should not be described as a stronger version of SUN or as a feature that automatically verifies the entire pharmaceutical supply chain. For a more detailed model comparison, seeNTAG 223 DNA vs. NTAG 224 DNA.

NTAG 223/224 DNA Technical Specifications

These are IC-level specifications. They do not define the read range, peel strength, water resistance, print durability or service life of every finished label. The finished product depends on antenna design, substrate, adhesive, label converting, package materials, placement and operating conditions. Confirm the final construction through sample testing. Refer to NXP's NTAG 223/224 DNA product documentationfor the current chip information and data sheets.

How Does NFC Authentication Relate to Pharmaceutical Serialization and Regulation?

NFC authentication should be planned as an additional product-authentication channel that works alongside the identification, safety-feature and traceability systems required in each market.

For example, the European Commission’s Falsified Medicines framework requires safety features such as a unique identifier and an anti-tampering device on the outer packaging of certain medicines. In the United States, the DSCSA requires interoperable, electronic tracing of certain prescription drugs at the package level. GS1 Healthcare identifies GS1 DataMatrix as its preferred 2D data carrier for healthcare packaging and describes the use of GTIN, batch/lot number, expiry date and serial number.

An NFC tag can complement a required barcode or other approved packaging feature by providing a separate tap-based interaction or an additional cryptographic check. Pharmaceutical manufacturers should align NFC authentication with the applicable EU Falsified Medicines Directive, DSCSA, GS1 standards and local serialization rules, and should confirm with their regulatory and serialization teams the required identifiers, data carriers, tamper-evident features, repositories, reporting and validation requirements in each destination market.

Custom NFC Label Options for Pharmaceutical Packaging

The physical label should be designed around the package and verification workflow. Depending on the selected chip and construction, project variables may include:

·Label format: custom NFC tag, security label, packaging label or inlay.

·Dimensions and shape: matched to the available panel, bottle, cap or carton area.

·Substrate and adhesive: paper, PET, PVC or other suitable constructions, subject to packaging compatibility and sample approval.

·Antenna configuration: designed around the label dimensions, package material and intended tap location.

·Printing and variable data: logo, brand colors, batch-related print, QR code, barcode or serial number as specified.

·Encoding and personalization: UID association, NDEF data and the agreed authentication configuration.

·Tamper evidence: visible VOID or other tamper-evident construction where required and validated as a physical label feature.

·Packaging: roll, sheet or other agreed delivery format, subject to the production setup.

Available combinations must be confirmed for the selected chip, antenna, adhesive and package. Do not assume that every material, label size or tamper-evident feature can be combined without redesign and testing.

What Should Buyers Test Before Bulk Production?

1. Chip and configuration check: verify the selected IC model, memory configuration, NDEF structure and agreed security settings.

2. Authentication workflow: confirm that valid tags are accepted and that altered, invalid, duplicated or unexpected messages are handled according to the project's defined rules.

3. Key-management process: verify who provisions, stores, uses, rotates and revokes keys. Do not expose production secrets in general manufacturing documentation.

4. Device compatibility: test representative NFC-enabled phones and readers, operating systems and the intended app or browser flow.

5. Installed read performance: test the label after application to the real carton, bottle, cap or blister-related packaging, at the intended tap position.

6. Physical label performance: inspect print, dimensions, die-cut, adhesive behavior, removal evidence and package fit against agreed acceptance criteria.

7. Data and record controls: check unique-item association, batch and expiry records, duplicate handling and the expected response when the backend is unavailable.

8. Production approval: document the approved sample, inspection plan, acceptance criteria, packaging format and order requirements before volume production.

Read range is not a fixed value that can be determined from the chip model alone. It depends on the antenna, label construction, package materials, phone or reader and installation environment. Test production-representative samples under the intended conditions.

Frequently Asked Questions

Can NTAG 223/224 DNA make a medicine impossible to counterfeit?

Yes. The IC can provide AES-128-protected dynamic NFC message authentication, and it can guarantee the authenticity or composition of the medicine by itself. The result depends on secure personalization, key management, backend verification, physical packaging design and operational controls.

Does NTAG 223/224 DNA replace a pharmaceutical 2D barcode?

Yes. Market-specific rules require a particular product identifier, barcode, anti-tampering device or interoperable tracing process. NFC can serve as a smarter and more secure anti-counterfeiting solution, replacing traditional QR codes on pharmaceutical products.

Which chip is better for pharmaceutical packaging, NTAG 223 DNA or NTAG 224 DNA?

NTAG 223 DNA provides 144 bytes of user memory and 32-bit password protection for memory access. NTAG 224 DNA provides 208 bytes and AES-128-based three-pass mutual authentication for protected memory access. Both support AES-128-protected SUN message authentication. Select the IC after defining the memory, authentication and integration requirements.

Can the tag store batch numbers and expiry dates?

Yes. The chips provide 144 or 208 bytes of user memory, so the data structure must be kept compact. A common design is to store a short identifier or URL and retrieve approved batch, expiry and product information from a connected system. The exact arrangement depends on the NDEF design and backend architecture.

Can an NFC label be used on a medicine bottle or blister pack?

Yes, but the finished package must be tested. Curved surfaces, liquids, metalized layers, foil, adhesive selection and antenna placement can affect read performance and physical durability.

Does NTAG 223/224 DNA include a tamper-evident function?

The standard chip functions described here do not by themselves provide a visible first-opening seal. Tamper evidence such as a VOID pattern or destructible label must be designed into the physical label and package construction and then tested.

Will every NFC smartphone verify the tag?

Not necessarily. Device hardware, operating system behavior, NDEF configuration and the verification experience can vary. Test representative phones and readers before deployment.

What information is needed for a quotation?

Provide the preferred IC, label or inlay format, dimensions, package material, adhesive or tamper-evident requirements, printing and variable-data needs, encoding workflow, estimated quantity, destination market, sample requirements and target schedule.
