1 Introduction

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 certified as NFC Forum Type 4 Tag [Certifcation ID: 58515] [15]

and is also compliant to ISO/IEC14443-4 [4], ISO/IEC 7816-4 [7] 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.

1.1 Contactless energy and data transfer

Communication to NTAG 413 DNA can be established only when the IC is connected

to an antenna. Any form factor and antenna class type according to ISO/IEC 14443-1

[1] is possible to design with NTAG 413 DNA ICs. Few antenna design examples with

guidelines are in NTAG antenna design application note [12] .
