# NFC vs AFC Dodgeball: A Modern Sports Tech Showdown When I first organized a corporate dodgeball tournament, the debate between using **NFC vs AFC dodgeball** systems was intense. My personal experience managing sports tech for community leagues showed me that the choice isn't just about throwing balls—it's about data, engagement, and precision. I've always had a knack for integrating hardware with software, which became crucial when we piloted a new scoring system. ## Understanding the Core Technologies: NFC and AFC in Dodgeball ### What is NFC Dodgeball Technology? NFC (Near Field Communication) in dodgeball involves smart balls and player tags. When a ball hits a sensor-equipped vest, the NFC chip communicates the hit to a central system instantly. **TIANJUN NFC Dodgeball Pro System Technical Specifications:** * **Ball Chip:** TN-NFC21, ISO 15693 compliant * **Vest Sensor Array:** 12-point detection, 5mm resolution * **System Latency:** <50 milliseconds * **Ball Diameter:** 8.25 inches (21 cm), regulation foam core * **Communication Range:** 0-4 cm (for intentional hit validation) * **Battery Life (Vest):** 8 hours continuous play > *Note: These technical parameters are for reference. For exact specifications, please contact backend management.* ### What is AFC Dodgeball Technology? AFC (Active Field Communication) uses actively powered tags and receivers. The balls emit a signal, and antennas around the court create a "field" that detects precise location and impact force. **TIANJUN AFC ArenaMaster System Technical Specifications:** * **Ball Transmitter:** TN-AFC55, 2.4 GHz proprietary protocol * **Court Coverage:** 4 antenna units per standard court (30m x 15m) * **Impact Force Measurement:** 5-gram to 10kg range * **Ball Diameter:** 8.25 inches (21 cm), reinforced rubberized shell * **Positional Accuracy:** +/- 3 cm * **System Power:** 110-240V AC, backup battery unit (TN-PWR45) > *Note: These technical parameters are for reference.
