Tamper-Evident NFC Packaging Seal Label | NXP NTAG® 424 DNA TagTamper | 25 × 51mm
The ForNext 25 × 51 mm tamper-evident NFC packaging seal label combines a Ø25 mm round NFC sensing area with an extended tamper-detection tail. It is designed to bridge the opening point of bottles, jars, cartons, boxes and other packaging closures.
Powered by the NXP NTAG® 424 DNA TagTamper chip, the label supports secure product authentication, packaging integrity verification and brand protection. It operates at 13.56 MHz and complies with ISO/IEC 14443 Type A, ISO/IEC 14443-4, ISO/IEC 7816-4 and the NFC Forum Type 4 Tag specification.
The round NFC section can be positioned on the main packaging surface, bottle cap or container lid, while the extended tail runs across the opening edge. When the package is opened, the connected tamper loop is broken, allowing the chip to report the changed seal status during a subsequent NFC tap.
NTAG® 424 DNA TagTamper also supports AES-128 cryptographic authentication and Secure Dynamic Messaging. Each tap can generate dynamic authentication data for verification by a compatible backend platform, helping brands distinguish genuine products from copied URLs, duplicated QR codes and conventional static NFC labels.
The label measures 25 mm across the round head and 51 mm in overall length, including the tail. Paper, PET and other synthetic face materials are available, together with custom printing and adhesive options for different packaging surfaces.
Typical applications include:
- Packaging integrity verification – detect whether a bottle, carton, box, jar or container closure has been opened.
- Product authentication – allow customers, distributors and inspectors to verify genuine products using an NFC-enabled smartphone.
- Pharmaceutical and healthcare packaging – combine digital authentication with electronic opening-status detection.
- Cosmetics and skincare – protect premium bottles, jars, gift boxes and branded packaging.
- Wine and spirits – apply across caps, closures or presentation boxes for authentication and opening-status verification.
- Luxury and high-value goods – protect electronics, accessories, collectables and limited-edition products.
- Secure smart packaging – connect verified products to registration, warranty, traceability, instructions or personalised digital content.

This 25 × 51 mm NTAG® 424 DNA TagTamper packaging seal label combines cryptographic product authentication with electronic opening-status detection. It is suitable for brands requiring stronger protection than conventional destructible labels, static NFC tags or printed security seals.
A complete authentication and tamper-verification solution normally requires secure chip personalisation, controlled cryptographic keys and a compatible backend platform. The tail must be correctly positioned across the packaging opening so that normal product access breaks the connected tamper loop.
