Possible reasons for ETC recognition failure are as follows: 1. Excessive vehicle speed causing unsuccessful information reading. 2. Some vehicles' front windshields may shield microwave signals due to metal explosion-proof film, leading to ETC recognition failure. 3. Possible ETC device issues, such as dead battery or loose card, may prevent smooth recognition in ETC lanes. Extension: ETC, short for Electronic Toll Collection, is a toll collection method promoted by the state in recent years to improve highway traffic efficiency through electronic toll stations. ETC generally consists of several components: the device installed on the vehicle is called OBU, specifically used for card insertion. Then there's your bank card for fee deduction. Finally, there's the ETC scanning device installed at toll stations, specifically for scanning your ETC card.
