China petrochemical refueling card circle.
Allocation is only to allocate the balance of the customer's main card account to the reserve account of the secondary card. At this point, the customer needs to deposit the amount in the reserve account into the IC card chip, and the amount will be displayed on the tanker.
Pledged deposit is to deposit the funds that customers pre-charge online or pre-allocate from the main card to the auxiliary card of the fuel card (at this time, the funds enter the reserve account) into the IC card chip of the fuel card (or auxiliary card) (we call it the card wallet). There is no deposit, and the funds only enter the reserve account in the background of the system, not on the fuel card; After the deposit, the system background and the fuel card funds are the same.
At present, bank cards are all online transactions. The customer swipes the bank card at the merchant, and the merchant needs to connect with the back-office system of the bank to deduct money. When the communication network is blocked, it is impossible to swipe the card, and customers need to pay by other means (such as paying cash).
The fuel card uses offline consumption. When the customer takes the fuel card to the gas station to refuel, because the money has been circled in the card wallet, he can directly swipe his card on the tanker for consumption. Even if the network is unavailable, it will not affect customers' refueling.
Customers need to hold cards at gas stations or card outlets in the provincial intranet for manual deposit, and employees of Sinopec gas stations or recharge outlets handle deposit business for customers.
