So which bank has the best ETC processing among many banks? Which bank has the best ETC offer? At present, China Construction Bank, Agricultural Bank of China, 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. 1Industrial and Commercial Bank of China: Enjoy a 95% off pass discount, free OBU equipment, and enjoy full gas discounts by binding an ICBC credit card. 2 Agricultural Bank of China: 10% off on tolls, with a maximum discount of 100 yuan per month; free OBU; 50% off on gas, and monthly rebates. 3 China Construction Bank: 9.5 pass discount; enjoy 3 free roadside assistance services per year; enjoy designated car wash services with one purchase per month; discount on refueling, 100 off on first recharge over 200; free offline annual vehicle inspection. 4 Postal Savings Bank: 20% off on highways on weekends; full discounts on purchases at Guangbai Department Store; car wash service in September; 50 rebates for 500 refueling, with a maximum discount of 100 yuan per crossing.

In addition, there are other banks that can handle ETC for free, such as Bank of Communications, Shanghai Pudong Development Bank, etc.
