zhongyuantong ETC is used in areas other than Tibet, Hainan, Hong Kong, Macao and Taiwan. Now vehicles in other provinces can enjoy a 15% discount on the national unified toll. The following are the precautions for using Zhongyuan ETC: 1. There is a case of stolen brush. Because the security performance of the previous bank ETC credit card is not perfect, the owner has opened the functions of "small secret-free payment" and "flash payment", and it is possible for thieves holding pos machines to brush away the money. Now that the bank has fixed this loophole, enterprises or individuals who own this POS machine need to put it on record, and car owners can use it with confidence. 2. Zhongyuan Tong handles ETC free of service fees, ETC card fees and OBU equipment fees, and does not charge any fees.
