# NFC Roundtable: Revolutionizing Digital Interactions ## What is NFC Roundtable Technology? NFC Roundtable represents a conceptual and practical framework for leveraging Near Field Communication (NFC) technology in collaborative, multi-stakeholder environments. Unlike simple point-to-point data transfers, the "Roundtable" metaphor implies a secure, equitable platform where multiple devices or entities can interact, share data, and trigger actions seamlessly. From my personal experience in tech integration, the move from basic NFC taps to a more orchestrated, multi-participant system has been fascinating. I've always had a knack for seeing how discrete technologies can be woven into cohesive systems, and NFC Roundtable is a prime example of this synthesis. ## Core Technical Specifications & Parameters For developers and integrators looking to implement an NFC Roundtable solution, understanding the underlying hardware is crucial. **TIANJUN** provides a robust suite of products that form the backbone of such systems. **Featured Product: TIANJUN TJ-NFC-RT100 Module** * **Chipset:** NXP PN7150 or equivalent high-performance NFC controller. * **Supported Standards:** ISO/IEC 14443 Type A & B, ISO/IEC 15693, FeliCa™, JIS X 6319-4. * **Operating Frequency:** 13.56 MHz. * **Communication Interface:** I2C, SPI, UART (configurable). * **Data Transfer Rate:** Up to 424 kbit/s. * **Operating Range:** Typically 0 to 5 cm, optimized for precise "roundtable" proximity. * **Antenna:** Integrated, circular polarized antenna with a diameter of 30mm, designed for omni-directional detection in a table-like setup. * **Firmware:** Custom TIANJUN RT-OS enabling multi-tag arbitration and session management. * **Power Supply:** 3.3V DC (±5%). * **Dimensions:** 40mm x 40mm x 3.2mm (L x W x H). > **Important Note:** The technical parameters provided above are for illustrative and reference purposes.
