NFC (Near Field Communication) technology has become integral to modern communication, with its applications extending from mobile payments to secure access control. NFC NTAGs are a family of NFC tags based on NXP’s NTAG IC (integrated circuit) series, designed for diverse NFC solutions. They offer various storage capacities, read/write cycles, and unique features tailored to different needs. This guide dives into the popular NTAG types—NTAG213, NTAG215, NTAG216, and NTAG424 DNA—to help you understand their specifications, storage capacities, and ideal use cases.
1. NTAG213: Compact and Reliable for Basic Applications
Memory Capacity: 144 bytes (180 bytes total)
Typical Uses: Smart posters, product labels, business cards
Features: UID mirror, ASCII mirror, fast read command, and counter for tracking reads
NTAG213 is the entry-level tag in the NTAG family, providing just enough storage for simple NFC applications. With 144 bytes of user memory, it’s ideal for basic tasks like linking to a URL, storing a small amount of text, or encoding business card information. This tag is popular for smart posters and product labels due to its cost-effectiveness and ease of use.
2. NTAG215: Versatile Storage for Toys and Loyalty Programs
Memory Capacity: 504 bytes (540 bytes total)
Typical Uses: Gaming accessories (such as Nintendo Amiibo), loyalty cards, secure access control
Features: UID mirror, ASCII mirror, counter, and increased data storage
With a larger memory capacity than NTAG213, NTAG215 offers more versatility for data storage. It’s commonly used in interactive toys and loyalty programs where slightly more data storage is necessary. For example, the popular Nintendo Amiibo uses NTAG215 tags to store game data. It’s also used for applications that require added security, such as loyalty cards and simple secure access systems.
3. NTAG216: Maximum Storage for Extensive Information
Memory Capacity: 888 bytes (924 bytes total)
Typical Uses: Contact cards (vCards), extensive product details, contactless marketing campaigns
Features: Similar to NTAG213 and NTAG215 but with expanded storage
NTAG216 provides the most storage in the NTAG family, making it perfect for data-heavy applications. With 888 bytes of memory, it can store more extensive information, such as vCards, large product details, or interactive marketing content. Its large storage capacity and compatibility with most NFC-enabled devices make it a preferred choice for applications where more data needs to be transmitted.
4. NTAG424 DNA and NTAG424 DNA TagTamper: High-Security NFC Solutions
Memory Capacity: 244 bytes (NTAG424 DNA) or 888 bytes (NTAG424 DNA TagTamper)
Security Features: AES-128 encryption, message authentication, password protection
Tamper Detection: NTAG424 DNA TagTamper offers a unique tamper-detection feature
Typical Uses: Anti-counterfeiting, secure access, tamper-proof packaging
For applications that demand high security, NTAG424 DNA and NTAG424 DNA TagTamper are excellent options. These tags feature AES-128 encryption and message authentication for secure data transmission, making them ideal for anti-counterfeiting measures and secure access systems. NTAG424 DNA TagTamper includes an additional tamper detection feature, making it suitable for tamper-proof packaging. This added security helps protect the authenticity of products and adds a layer of protection against counterfeiting.
