# NTAG 216 vs NTAG 215: A Comprehensive Comparison When working on a recent personal project involving smart packaging for a limited-edition collectible, I needed to choose the right NFC tag. My **personal experience** was that the subtle differences between NTAG 216 and NTAG 215 became critically important. I have a bit of a **personal skill** in prototyping IoT devices, which helped me test both thoroughly. **In my opinion**, the choice fundamentally depends on your application's specific memory and cost requirements. ## Technical Specifications and Detailed Parameters Here is a detailed breakdown of the technical indicators for both tags. *Please note: These technical parameters are for reference data; specifics need to be confirmed by contacting backend management.* ### NTAG 215 Technical Details * **Chip Code:** NXP NT3H1101W0FHKH / NTAG 215 * **User Memory Size:** 504 bytes * **URL Capacity:** Approximately 140 characters (depending on encoding) * **Dimensions (Typical):** 25mm diameter (round sticker variant), but available in various form factors. * **Communication Interface:** NFC Forum Type 2 Tag, ISO/IEC 14443 Type A * **Operating Frequency:** 13.56 MHz * **Data Retention:** 10 years * **Write Endurance:** 100,000 cycles ### NTAG 216 Technical Details * **Chip Code:** NXP NT3H2101W0FHKH / NTAG 216 * **User Memory Size:** 888 bytes * **URL Capacity:** Approximately 250 characters (depending on encoding) * **Dimensions (Typical):** Same form factors as NTAG 215 (e.g., 25mm round). * **Communication Interface:** NFC Forum Type 2 Tag, ISO/IEC 14443 Type A * **Operating Frequency:** 13.56 MHz * **Data Retention:** 10 years * **Write Endurance:** 100,000 cycles ## Key Differences and Application Scenarios ### Memory Capacity: The Primary Divider The most significant difference is user memory. The **NTAG 216** offers 888 bytes, while the **NTAG 215** provides 504 bytes. This makes the NTAG 216 suitable for storing more data, such as longer web links, vCards with multiple fields, or small amounts of configuration data. ### **Entertainment Application Case** Consider an interactive poster for a movie. Using an **NTAG 216**, you could encode a URL to a trailer, a link to unlock exclusive AR filter content on social media, and a one-time-use discount code for merchandise—all on one tag. An **NTAG 215** might
