Practical application of circular storage
There are many ways to realize the self-help circle of banks and schools. The main ways of deposit transaction are self-service deposit transfer (credit card, contract signing) and background batch transfer (automatic and manual).
In order to protect the security of the cardholder's bank card information, it is necessary to sign and bind the bank account and the campus card account, and verify the binding relationship during the transaction to ensure the legitimacy of the card number information. The use process is as follows:
1. Teachers and students who need to transfer money from the bank to the school sign transfer business agreements with the bank and the school, and set the transfer conditions (such as the lower limit of the account is lower than a set value, and the amount of each transfer from the personal account).
2. The system regularly checks the customer accounts of the system every day, forms a transfer application form from the list of people who meet the transfer conditions, and sends it to the bank through the agreed communication method.
3. The bank regularly checks the application documents every day, and decrypts them after receiving them to form a transfer result file.
4. Send it back to the application host. After the host receives it, it will make an account. If it succeeds normally, an exception handling record will be made.
5. Teachers and students with campus cards can receive the corresponding transfer amount through the self-service cashier.
