2. After the 2.pos machine is turned on, we will check in first. Usually we press the 1 key, enter the teller number 0 1 and-enter the password 0000, and then wait for the pos machine to connect.

3. In this case, the pos machine will be opened. At this time, we can see some functions displayed on the machine.

We just need to enter the amount payable by the customer, press OK after it is correct, then ask the customer to check, enter the password on the keyboard, and then press OK.

4. Finally, the pos will automatically print the consumer receipt, so that the customer can check it again and sign the receipt.
