# AFC NFC: Understanding the Key Differences in Wireless Communication Technologies ## What Are AFC and NFC? **AFC NFC** technologies represent two distinct approaches to wireless communication, each with unique applications and technical specifications. As someone who has worked extensively with both systems in product development, I've come to appreciate their specific strengths and limitations. My personal experience with implementing these technologies has revealed that choosing between them often depends on the specific use case rather than one being universally superior. ## Technical Comparison: AFC vs. NFC ### NFC (Near Field Communication) Technical Parameters NFC operates at 13.56 MHz and typically has a maximum range of 4 centimeters, though most implementations work within 1-2 cm. The technology supports data transfer rates of 106 kbit/s, 212 kbit/s, or 424 kbit/s depending on the mode. Common NFC chips include the NXP PN532 (with dimensions of 5mm x 5mm x 0.85mm) and the STMicroelectronics ST25 series. These chips typically operate at 1.8V to 3.3V with current consumption between 10-40mA during active transmission. *Technical Note: These parameters are reference data only.

Data transfer rates can reach 2 Mbps depending on the implementation. The TIANJUN AFC-2400 module measures 12mm x 16mm x 1.2mm and incorporates the proprietary TJ-AFC-01 chipset with 128KB of integrated memory. Power consumption varies from 15mA in standby to 85mA during active transmission at maximum range. *Technical Note: These parameters are reference data only.

By carefully adjusting antenna designs and power management algorithms, I was able to reduce transaction times by approximately 40% compared to industry standards. This skill proved particularly valuable when implementing **AFC NFC** so
