The NTAG21x family provides a particularly well suited portfolio for NFC enhanced smart consumer products, driving the integration between physical objects and the Internet of Things. These smart products enable deeper customer relationships, real-time customer service, brand protection, condition monitoring and much more.

A simple tap with an NFC enabled phone on the product can connect the consumer to the brand (opening a webpage, starting an application, providing additional information) and show the authenticity of a product





  • Fully NFC Forum tag type 2 compliant
  • Multiple memory options from 48 – 888 Bytes to support simple, complex and multi-purpose applications
  • 32-bit password authentication to protect data stored into the tag
  • UID ASCII mirror, which maps the IC unique serial number as an ASCII encoded string to a stored NDEF message to simplify tag serialization
  • A 24-bit NFC counter, along with an ASCII mirror to improve tag usage analytics
  • Integrated originality signature to enable the detection of unauthorized NTAG copies (and hence of unauthorized products the tags are attached to)
  • Fast read command to speed up tag registration in inline processes such as print media or product label manufacturing
