On the morning of November 8th, at the Zhuhai Highway Port of the Hong Kong-Zhuhai-Macao Bridge, Xue Ming, an athlete from the Tianjin team, leaned forward on his bicycle. The moment he whizzed past the inspection area at 40 km/h, the electronic screen at the race command center simultaneously lit up with "Identity Verification Passed". Without a single stop or delay, in this Men's Individual Road Cycling Race of the 15th National Games (XIV National Games) that connects Zhuhai, Macao, China and Hong Kong, China over 250 people (including 103 athletes), 68 support vehicles and 126 pieces of competition materials all achieved "zero-wait" clearance during six cross-boundary crossings along the 231.8-kilometer race route. Behind this lies an "invisible protective network" built by RFID (Radio Frequency Identification) technology, which is reshaping the new paradigm of cross-boundary race clearance with its technical strength.

As the first cross-boundary event in the history of the National Games, the core challenge of "seamless clearance" is to solve three major problems: "accurate verification during high-speed movement, simultaneous supervision of multiple subjects, and stable operation in extreme scenarios". Last June, Zhuhai Transportation Internet of Things Co., Ltd., which once developed the "Macao Single-Plate Vehicle Inspection-Exempt Entry/Exit Hengqin Management System", was commissioned again to develop the clearance system for this event. "This is China's first cross-boundary race clearance solution with no prior examples to follow; technological breakthroughs are essential to make it work," said Wu Wuhui, General Manager of the company. The team finally locked onto RFID technology as the core support, which works in synergy with China's domestically developed Beidou Navigation System to build an all-dimensional intelligent supervision system covering "people-vehicles-materials".

Technological Breakthrough: Three Core Advantages of RFID Solving Customs Clearance Pain Points

Wu Wuhui stated that the solution adopts "invisible" technical services to balance precise supervision and event rhythm, with RFID technology being the key to breaking bottlenecks. First, non-contact high-speed identification enables zero-latency identity verification even as athletes ride at high speeds, eliminating the need for stops. Second, multi-tag concurrent reading allows batch data verification—checking information for over 250 people and 60+ vehicles in milliseconds, with an error rate below 0.1%. Third, full-link real-time synchronization uses encrypted chips to store core data and link to the command center system, realizing the goal of "data traveling more so people travel less" .

Extreme Scenario Verification: From Rainstorm Tests to "Comfort Wristband" Experience Upgrade

During the rainstorm-hit test event on November 24, 2024, RFID devices malfunctioned due to water ingress. The team upgraded the system within 3 days—adding professional waterproof coatings, delivering 20 backup units, and switching to wired transmission with standby modules to create a "double safety net" for extreme conditions. Simultaneously, technological humanistic care was enhanced: a flexible "comfort wristband" was designed to ensure skin-fitting comfort without hindering riding. Its built-in emergency response module demonstrates technological warmth—upon receiving a withdrawal signal, the RFID tag immediately triggers alerts to border control and customs authorities , buying time for emergency handling.

Actual Combat Success: Zero-error Clearance Validates Technical Strength

On the race day, athletes like Xue Ming passed through ports at full speed without noticing any inspection. All 103 athletes, over 150 staff, 68 vehicles, and 126 pieces of materials achieved "zero-error, zero-delay, zero-fault" clearance , fully verifying RFID's accuracy, real-time performance, and adaptability.

This cross-boundary event not only showcased athletes' perseverance but also built a "Chinese model" for cross-boundary event clearance using RFID technology. Its technical logic and practical experience now provide replicable intelligent solutions for cross-boundary flow of people and goods in the Guangdong-Hong Kong-Macao Greater Bay Area, extending "seamless clearance" from sports events to broader public services.
