Interactive experience improved ATM machine most commonly used operations

For the ATM machine, I don't think everyone has used it, I have seen it? Ha ha.
The most common operation of the ATM machine has the balance, withdrawal, and transfer (other features are not discussed).
Generally, you will insert the bank card into the slot, it will prompt you to enter your password. After verify the password, you will come out a prompt menu. Some is a currency choice. Some direct out "Query balance, withdraw, transfer, exit" big buttons.
Ok, think about it, you use the ATM machine to make it easy to manage your property, you don't have to queue in the counter, you will not be bound by the bank, at the same time, you can use money, that is, Don't have to go to a specific bank, such a feature determines that the ATM machine can provide you with the value outside of the bank counter service.
Then, the purpose of "Query Balance" is to understand the balance of bank cards. The purpose of "withdrawal" is to take out cash. In the process of withdrawal, will you pay attention to the balance before withdrawal, and the balance of withdrawal, and whether there is any error with your cash in your hand?
I seem to hear the voice of a bank staff: "What? Suspected that we have an error, our computer system is all IBM, safe and accurate!"
Perhaps we do not have to doubt what, but provide the amount of changes before and after withdrawal, will help the payee clearly know the results of the withdrawal, in other words, deterministic let us reduce anxiety.
The same is true for transfer, gives us a change in the amount before and after transfer, and let us be more assured to transfer.
Further considering that since the three basic functions care the balance, is it more friendly after the password is verified?
There is another problem with the transfer, usually, the ATM opportunity allows you to enter the other party account, then enter the amount of transfer, then ask you to confirm the transfer.
During this process, we are most worried about being turned to the wrong person. It is possible to knock the wrong account. It is also possible to have a wrong account; worrying the possibility of an error is relatively small, because the numbers are simple and clear.
When transferring, ATM only allows us to enter two times account, and what is the inspection measures it can only be an input error, not to care about our true purpose: turn a certain amount of money to the correct account, if entering the first pass At the time of the account, the other party's account name is displayed. In this way, the opportunity to make an error and the fear of an error will not be greatly reduced?
Therefore, I have the proposal for the basic interaction of ATM is:
1: After verifying the password, give the balance (at least the balance of the default currency); 2: After the payment is completed, the balance change before and after the withdrawal is clear; 3: When transferring, give the other account name, To give the balance change before and after the withdrawal.
Again, the principle involved here is that the determined information allows users to reduce anxiety.
If there is a problem that involves security issues, there must be a solution to security issues.
In addition: The operation of online banking can also be considered.
Regarding determinism, let us reduce anxiety:
Please refer to the timing device of the traffic intersection. When it is clear that you can pass or wait for how long you have to wait for more time, the driver can consider and decide.
