What is the purpose of the motor vehicle electronic identification?

[StCharles]

Motor vehicle electronic identification is used to achieve vehicle identity recognition and dynamic monitoring in high-speed motion states, along with traffic flow monitoring, and to promote intelligent urban traffic management. Motor vehicle electronic identification, also known as the electronic ID card for vehicles, stores license plate number information in a radio frequency tag, enabling automatic, non-contact, and non-stop vehicle identification and monitoring. The working principle of motor vehicle electronic identification is as follows: when passing through checkpoints, major intersections, or locations equipped with roadside units, the ultra-high frequency electromagnetic waves emitted by the card reader are received by the electronic license plate, converted into electrical energy to activate the chip. After verifying the identity of the card reader and other information, the chip sends the required data back to the card reader, which then transmits this information to the command center.
