The term "NTAG21x" refers to a series of NFC (Near Field Communication) tags developed by NXP Semiconductors. The "21x" in the name indicates that these tags belong to a family of NFC tags, and the specific model numbers can vary within this series.
Each model within the NTAG21x series may have slightly different specifications, features, or memory capacities. The most common model within this series is NTAG215, which is often used in various applications due to its versatile features, such as rewritability and a memory capacity of 540 bytes.
Here are some key points about the NTAG21x series:
1. Memory Capacity: The memory capacity of NTAG21x tags can vary, but it's commonly around 144 bytes, 504 bytes, or 888 bytes, depending on the specific model.
2. Rewritability: NTAG21x tags are generally rewritable, allowing users to update or change the information stored on the tag multiple times.
3. Compatibility: These tags are compatible with a wide range of NFC-enabled devices, including smartphones, tablets, and other NFC readers.
4. Applications: NTAG21x tags find applications in various fields, including marketing, access control, product authentication, and interactive experiences.
5. Security Features: Some models within the series may include features such as password protection, adding a layer of security to the stored data.
If you have a specific model within the NTAG21x series in mind, such as NTAG213, NTAG215, or NTAG216, you may want to check the specifications for that particular model, as there can be slight variations in terms of memory capacity and features. These tags are commonly used in projects that leverage NFC technology for communication between physical objects and digital devices.
