There are several different types of NFC (Near Field Communication) tags available, each with specific features, capabilities, and use cases. The different types of NFC tags are defined by NFC Forum standards, which specify various parameters such as memory capacity, data transfer speed, and application areas. Here are some common types of NFC tags:
1. NFC Type 1 Tags:
- Low-cost and limited memory capacity.
- Typically used for simple applications like storing URLs or short text.
- Read and re-writable.
- Commonly used for promotional purposes and basic data sharing.
2. NFC Type 2 Tags:
- Widely used in marketing, product authentication, and access control.
- Larger memory capacity compared to Type 1.
- Supports additional features like password protection.
- Read and re-writable.
3. NFC Type 3 Tags:
- Less common and often used in specialized applications.
- Typically used in contactless payment cards and other specific use cases.
- Offers more memory and data transfer capabilities.
4. NFC Type 4 Tags:
- Provides higher security and encryption features.
