# RFID vs NFC Card: Understanding the Differences and Applications ## Introduction to RFID and NFC Technology RFID vs NFC card technologies are often mentioned together, but they serve different purposes with varying capabilities. As someone who has worked with both technologies for over a decade, I've implemented numerous solutions ranging from inventory management to contactless payment systems. My technical background in embedded systems gave me a unique perspective on how these technologies function at the hardware level. ## Technical Specifications and Parameters ### RFID Card Technical Specifications - **Frequency Range**: 125 kHz (LF), 13.56 MHz (HF), 860-960 MHz (UHF) - **Operating Distance**: Up to 12 meters for UHF systems - **Chip Examples**: EM4100 (125 kHz), NXP Mifare Classic 1K (13.56 MHz) - **Memory Capacity**: Typically 64 bits to 8 KB - **Power Source**: Passive (powered by reader), Active (battery-powered) - **Communication**: One-way (reader to tag) or two-way - **Dimensions**: Standard CR80 (85.6 × 54 mm) or custom sizes *Note: These technical parameters are reference data.

My first major project involved implementing a UHF RFID system for warehouse inventory tracking, where the extended range (up to 12 meters) proved invaluable for scanning multiple pallets simultaneously. In contrast, NFC's limited range (deliberately designed for security) makes it ideal for applications requiring intentional interaction, such as contactles
