Does ETC have a front and back side?
1 Answers
ETC cards have a front and back side. The front side of the ETC card should face the driver, while the back side faces the windshield, with the chip portion inserted into the OBU device. Below is relevant information about vehicle ETC: 1. Charging methods: Currently, ETC devices come in two power supply modes: solar panel charging and wired charging. Both types of ETC electronic tags contain internal batteries. Solar-powered ETC devices do not require charging during daily driving, with the lithium battery lasting approximately 3 years under normal use. 2. Charging recommendation: For users who do not frequently use ETC, it is recommended to charge the ETC device once every 3 months to effectively mitigate the impact of natural battery discharge on its lifespan.
