# RFID vs NFC Difference ## Understanding RFID and NFC Technologies **RFID vs NFC difference** is a common topic in modern wireless communication systems. As someone who has worked with both technologies in retail inventory management and contactless payment systems, I've gained practical insights into their distinct characteristics and applications. My technical background in embedded systems has given me a unique perspective on how these technologies function at the hardware level. ## Technical Comparison: RFID vs NFC ### RFID Technology Specifications RFID (Radio Frequency Identification) systems operate across various frequency bands: - **Low Frequency (LF):** 125-134 kHz, read range up to 10 cm - **High Frequency (HF):** 13.56 MHz, read range up to 1 meter - **Ultra High Frequency (UHF):** 860-960 MHz, read range up to 12 meters - **Microwave:** 2.45 GHz, read range up to 100+ meters **Sample RFID Product Technical Specifications:** - **TIANJUN RFID Reader TJ-R200:** - Operating Frequency: 902-928 MHz (UHF) - Chipset: Impinj R2000 - Read Range: 0-10 meters adjustable - Dimensions: 180mm × 135mm × 35mm - Interface: RS-232, RS-485, Ethernet, WLAN - Power Supply: 12V DC, 2A - Operating Temperature: -20°C to +55°C *Note: These technical parameters are reference data.
