Any major bank will do, mainly depending on which bank you often use. ETC has two charging methods. One is a savings card, that is, the bank card corresponding to the ETC card is bound, and you can transfer money to recharge it. The other is debit card, which means you can apply for a credit card. This credit card can be directly recharged by inserting it into ETC, and can also be used as a credit card. I use this. Shenzhen Credit Card ETC card is only available in China Construction Bank and China Agricultural Bank. Originally, I accompanied China Merchants, but China Merchants didn't have a debit card, so I had to set up the Agricultural Bank of China. Agricultural Bank of China still has some fee concessions, and I wonder if there will be any in the future.
