# NFC 74-100: The Ultimate Guide to High-Frequency NFC Technology ## What is NFC 74-100? **NFC 74-100** represents a specific high-performance category within Near Field Communication technology, operating at the standard 13.56 MHz frequency. This designation typically refers to NFC tags, chips, or systems with enhanced capabilities, often indicating a series or model range optimized for specific applications requiring robust performance, extended read ranges, or specialized data handling. From my personal experience working with various NFC solutions, I've found that **NFC 74-100** products consistently outperform standard tags in challenging environments. I recall implementing a museum exhibition system where we needed reliable reads through protective glass cases – standard tags failed frequently, but the **NFC 74-100** series maintained near-perfect reliability throughout the six-month exhibition. ## Technical Specifications of NFC 74-100 Products ### Detailed Technical Parameters **Chip Specifications:** - **Primary Chip Code:** NXP NTAG 21x series (specifically configured for 74-100 performance profile) - **Alternative Chip:** STMicroelectronics ST25TA series (high-performance variant) - **Memory Capacity:** 888 bytes to 4KB user memory (depending on specific 74-100 variant) - **Data Retention:** 25 years minimum - **Write Endurance:** 100,000 cycles minimum **Physical Dimensions (Common Variants):** - **Disc Format:** 25mm diameter × 0.8mm thickness - **Card Format:** ISO/IEC 7810 ID-1 (85.6mm × 54mm × 0.84mm) - **Sticker Format:** 50mm × 50mm × 0.2mm - **Industrial Format:** 30mm × 30mm × 1.5mm (enhanced durability) **Performance Parameters:** - **Operating Frequency:** 13.56 MHz ± 7 kHz - **Read Range:** 8-12 cm (under optimal conditions) - **Data Transfer Rate:** 106 kbit/s to 424 kbit/s (adaptive) - **Anti-Collision:** Supports full anti-collision protocol - **Temperature Range:** -25°C to +70°C (operational) *Note: These technical parameters are reference data.
