Two ways: 1. At present, most gas stations charge by credit card, that is, the fuel card is recharged and paid directly by credit card, just like ordinary credit card consumption, so I won't go into details! Not every branch of Sinopec can swipe its card to see the gas station, but most branches of PetroChina can. 2. Download Sinopec/Petroleum APP, or add their official WeChat account to WeChat, recharge with fuel card-online banking, enter the fuel card number, choose UnionPay online payment, and enter the card number, expiration date, CVV verification code, mobile phone number and dynamic password of CCB to complete the online recharge of credit cards. It's all very simple ~
