NTAG^® 413 DNA Secure Unique NFC Message for Direct Access to Web Services

NTAG 413 DNA revolutionizes NTAG product portfolio by bringing AES cryptographic authentication and allows to automatically and securely connect to a web service by just tapping the tag without the need of a dedicated app installed on the mobile NFC device.

Besides the NXP^® originality signature and a 3-pass mutual authentication, it introduces a novel security feature called “Secure Unique NFC Message (SUN)”, which automatically generates tap-unique tag authentication data upon each read-out what enables dedicated unique communication to each user based on predefined criteria. No app (in NFC device) is required to generate this tap-unique data consisting of CMACed information derived from the chip UID, a tap counter, and contained data. An NFC enabled device can automatically connect to a web-based service and based on the information contained in URL, the device can check the tags authenticity and verify the information validity. NTAG 413 DNA offers flexibility to individualize the structure of this unique data set.

NTAG 413 DNA is an ideal solution to engage with consumers through dynamic content experiences, fully triggered by them and served in real time. By that it enables smarter marketing based on ongoing contextual and unique consumer engagement opportunities in a secure way. Applications include but are not limited to consumer engagement, brand protection, access control, one-time vouchers, and similar use cases where the proof of uniqueness, originality, and physical tag presence are required.

NTAG 413 DNA is a fully NFC Forum tag type 4 compliant IC and is also compliant to ISO/IEC14443-4, ISO/IEC 7816-4 file structure and APDUs format. Thanks to the high input capacitance (70pF), NTAG 413 DNA tag IC is particularly tailored for applications requiring small footprints, without compromise on performance. Small NFC tags can be more easily embedded into, e.g., product labels or electronic devices. The mechanical and electrical specifications of NTAG 413 DNA is tailored to meet the requirements of inlay and tag manufacturer.
