With the rise of ETC, major banks have launched ETC services, such as China Construction Bank, Postal Bank and Industrial and Commercial Bank of China. In order to attract more customers in the fierce market competition, major banks have also launched ETC preferential activities, so which bank has the largest ETC preferential treatment among many banks? Which bank is the best for ETC to go to? At present, China Construction Bank, Agricultural Bank, Industrial and Commercial Bank of China and Postal Savings Bank all handle ETC business for free. The main difference lies in the preferential activities after handling ETC. 1 Industrial and Commercial Bank of China: Enjoy a 15% discount, give away OBU equipment for free, and enjoy full fuel reduction if you bind your ICBC credit card. 2 Agricultural Bank: 10% discount on toll, with the highest monthly discount of 100 yuan; OBU is free of charge; Come on, 15% off, and enjoy a rebate every month. 3 China Construction Bank: 9.5 discount; Enjoy 3 free road rescue services every year; Spend a sum every month and enjoy the designated car wash service; When the fuel is full, the first recharge will be reduced by 200100; Free appointment for annual inspection of vehicles offline. Postal savings bank: 20% discount on weekend expressway; Shopping in Baiguang Department Store has been completely reduced; Car wash service in September; 500 for refueling and 50 for free, with the highest discount per trip 100 yuan.
