NTAG216

NTAG216 is a type of NFC (Near Field Communication) tag developed by NXP Semiconductors. It is part of the NTAG family of NFC tags, which are designed for various applications such as contactless payments, access control, and data storage. The NTAG216 tag has a storage capacity of 216 bytes, which is divided into 135 read-write user memory bytes and 81 read-only bytes. The read-only bytes include the tag's unique identifier, lock bits, and configuration data.

The NTAG216 tag operates at a frequency of 13.56 MHz and has a communication range of up to 10 cm. It supports the ISO/IEC 14443 Type A and B protocols, as well as the ISO/IEC 15693 protocol. This makes it compatible with a wide range of NFC-enabled devices, including smartphones, tablets, and point-of-sale terminals.

The NTAG216 tag is designed to be highly secure and reliable. It features a password-protected read-write memory, which can be used to store sensitive data such as access credentials or payment information. The tag also includes a one-way counter, which can be used to track the number of times the tag has been read or written to.

The NTAG216 tag is available in a variety of form factors, including stickers, key fobs, and smart cards. It can be programmed and personalized using a variety of tools and software, making it a versatile and cost-effective solution for a wide range of NFC applications.
