Yes, a credit card can be used as a debit card to bind up to 5 ETCs, but only one bank ETC card can be installed in a car, but ETC cards can be bound to pay for multiple cars, but the number of bank cards used by each bank for deduction is different.

Fill in the authorization of etc business deduction when handling etc card. When filling in the designated vehicles for binding payment, you can fill in 5 vehicles (more than 5 vehicles need to be filled in on a separate page). In other words, there is no limit to the number of vehicles specified by the etc card.

Precautions for using ETC:

1, ETC transaction area is 8m. When a vehicle is parked in front, it should keep a distance of more than 10m from the vehicle in front to prevent the vehicle in front from automatically paying fees.

2. The traffic identification speed of 2.ETC lane should be less than 20km/h, and the vehicle equipment information cannot be read because of the too fast speed.

3. Dismantling and moving OBU equipment without authorization, OBU power failure, ETC electronic tag falling off or loosening, ETC electronic tag may be invalid. You can take the ETC equipment to the bank or the highway for testing, and then reactivate it because the adhesive is loose. Pay attention to moisture-proof, waterproof and strong magnetic protection for the ETC electronic tag that you have regained.
