The operation of the bank counter staff is:
Pay the money first, and then put it on the account. After counting the cash handed in, swipe your card in the card reader according to the completed card application form, and then enter a series of information such as your name. You will also be asked to set the card password, usually twice. After the card is completed, select the registered account of the fund customer in the fund business option, and fill in the information such as name and address at the same time, and the system will generate a basic account, which is the only account corresponding to your card. Then choose the fund subscription option, choose the fund you want to buy, enter the amount you want to buy (premise: you have enough money in your card), and then print the transaction form, which may require you to sign for confirmation. Each of your funds has an account, but your customer number is unique.
When you redeem it, you transfer it from the fund account to your card deposit account. The fund account still exists, so when you want to buy it again in the future, you will use this fund account. If you no longer buy the fund, you can cancel the fund account, fill in the fund account cancellation form, and the bank staff will cancel the account.
