What does the bank do when you withdraw money from an ATM?

If you take an ICBC card to a CCB ATM and withdraw 100 yuan, then an interbank transaction has occurred. The process is very simple: The CCB system tells the ICBC system that an ICBC user wants to withdraw 100 yuan from me, can he do it? ICBC says that his ICBC account is enough to deduct 100 yuan, you can pay it for me first! The CCB ATM will spit out 100 yuan for you; So, you get the cash, and your ICBC account is reduced by 100 yuan. For you, the whole transaction is over. However, CCB first gave you 100 yuan on behalf of ICBC, and an interbank debt relationship is formed here: ICBC owes CCB 100 yuan. When and how to pay back this 100 yuan is a matter between banks, but only when this 100 yuan is paid off, the bank will regard the transaction as truly completed. It can be seen that a bank's interbank withdrawal can be divided into two steps: payment and settlement. - From you inserting the card to the ATM spitting out the banknotes, this process is called payment. - ICBC returns 100 yuan to CCB. This process is called clearing. The process of this interbank business in the CNAPS (China Advanced Payment System) system is as follows: You enter 100 yuan at the CCB ATM and press the withdrawal button (information flow) CCB sends the message information to UnionPay (information flow) UnionPay transaction system records the transaction data and sends the message to your issuing bank (ICBC) (information flow) ICBC deducts the fee from your card in real time, completes the real-time settlement, and replies to UnionPay (fund flow) UnionPay updates the transaction data and replies to the CCB ATM (information flow) UnionPay completes the clearing in its clearing system (information flow) UnionPay completes the funds transfer between the clearing accounts of ICBC and CCB through the large-value payment system (interbank clearing) (fund flow)
