NTAG® 413 DNA Secure Unique NFC Message for Direct Access to Web Services
This product is not recommended for new designs. Instead, we recommend to use our NTAG® 424 DNA / 424 DNA.
NTAG 413 DNA通过AES加密认证革新了NTAG产品组合，并采用轻刷标签安全地连接到Web服务，而无需在移动NFC设备上安装专用应用。
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具有灵活性，可实现这一独特数据集结构的个性化。
NTAG 413 DNA is an ideal solution to engage with consumers through dynamic content experiences, fully triggered by them and served in real time. 通过这种方式，它根据持续的情景和独特的消费者参与机会，采用安全的方式来实现更智能的营销。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是完全符合NFC Forum标签的4类兼容IC，并且也符合ISO/IEC14443-4，ISO/IEC 7816-4文件结构和APDU格式。由于NTAG 413 DNA标签IC具有高输入电容(70pF)，因此该产品尤为适用于要求具有小尺寸的应用，而不会降低性能。小型NFC标签可更轻松地嵌入产品标签或电子设备等目标中。NTAG 413 DNA的机械和电气特性可满足嵌票和标签制造商的要求。
