In recent years, with the rapid development of science and technology, intelligent transportation system has gradually become an important part of urban traffic management. Electronic Non-stop Toll Collection (ETC) system as an important part of it, greatly facilitates the travelers, but also raises a serious problem: how to prevent "rubbing" ETC, i.e., illegally borrowing other people's ETC tags, so as to circumvent the payment of transportation fees? In this context, RFID technology with its unique advantages and a wide range of applications, has become an effective tool to prevent the phenomenon of "rubbing" ETC.

At present, RFID technology in the strict prevention of "rubbing" ETC issues play a key role in its application in a number of aspects, for the establishment of a fair and equitable traffic order provides a solid guarantee:

1. Unique identification code: each ETC tag has been given a unique identification code, this identification code is similar to the vehicle's "identity card number", can be efficiently read and verified by RFID technology. This means that each vehicle has a unique "digital identity", so that the system can quickly identify the legitimate ETC tags.

2. Vehicle information records: RFID technology can accurately record the vehicle's passage information. Whenever a vehicle through the ETC pass, the system will automatically record the passage of time, location and other key information. These data are accurately stored, helping to ensure the accurate calculation of traffic costs, eliminating the errors that may be brought about by manual recording.

3. Real-time monitoring: RFID technology makes traffic monitoring more efficient and accurate. The system can real-time monitoring of vehicle traffic, quickly identify illegal ETC tags, that is, "rubbing" ETC phenomenon. Once the abnormal situation is found, the relevant departments can take immediate measures to ensure that the traffic order is not disturbed. 4.

4. Data encryption and security: In order to protect the security of traffic data, RFID technology supports data encryption and authentication. Traffic data will be encrypted during transmission to ensure that the information will not be illegally accessed or tampered with. In addition, only departments with authorization can access and manage the data to ensure the confidentiality and integrity of the data.

5. Automatic penalty system: Based on the data of RFID technology, the traffic management department can establish automatic penalty system more conveniently. Once someone is found to be illegally "rubbing" the ETC, the relevant data can be traced back to implement the appropriate penalties. This not only improves the efficiency of traffic management, but also increases the penalty for violations.
