The white NFC sticker offers a high level of security thanks to its integrated NTAG424 DNA chip and thus extends the familiar NTAG functions (UID, UID mirror, etc.) with additional cryptographic mechanisms, which enable the storage of AES-128 protected data, the generation of signatures, encrypted UID or randomized ID, among other things. This type of chip is therefore ideal for lotteries, authenticity certification or use in IoT applications.

Product description
NFC product
The NFC sticker made of PVC is characterized by a robust and waterproof material. With a format of 28 x 28 mm and a 3 mm hole in the middle as well as a material thickness of around 1.3 mm, the sticker is versatile. Thanks to the on-metal layer, the sticker also works on metallic or conductive surfaces. It is suitable for both indoor and outdoor use. The 3M adhesive layer ensures reliable adhesion to various surfaces.
NFC chip
The The NFC sticker made of PVC is equipped with the NTAG424 DNA, which is the successor to the NTAG413 DNA, adds additional functions and is recommended for use in applications with increased security requirements. The chipset supports AES-secured authentication of content as well as the Secure Unique Message feature (SUN) for generating a unique character string (HASH) based on a secret key. The generated character string can be appended to a stored NDEF URL, for example, and can then be checked on the server side. The basis for this is the previously configured shared secret. The full potential of the chipset can therefore only be exploited with the appropriate infrastructure.
The NTAG424 has a total capacity of 416 bytes, which is divided into two usable memory areas (256 bytes + 128 bytes). The 256 byte memory area offers space for NDEF messages whereas the 128 byte area is intended for encrypted data. Each chip has a unique serial number (UID) consisting of 7 bytes (alphanumeric, 14 characters). The NFC chip can be written to up to 200,000 times and has a data retention period of 50 years. Of course, the NTAG413 also has the standard functions of the NTAG series in the form of the UID ASCII mirror feature, with which the UID of the tag can be appended to the NDEF message, as well as an integrated NFC counter, which increases automatically during readout. Encryption is based on the AES-128 standard. Other features include an encrypted UID, a randomized ID and an ECC signature. The extended functions are not activated by default. The NTAG424 is compatible with all NFC-enabled smartphones and all ISO14443 end devices.
