A: how do you use an ATM card, billy? B: it's easy grandpa. Insert you card into the machine here. Then wait a moment. Ok. Now you enter your PIN. It should have four numbers. A: oh yes. I've got it written down here. Just a minute. B; you really shouldn't write it down. You should memorise it. You can change it to a more convenient number if you like. A: ok, I've entered my PIN. There are several options on the screen. I guess I just choose which service I want, don't I ？ B: Yes. Choose the service you need to use. If you choose to withdraw money, the machine will ask you how much you want. A: I can just enter the amount using the key, right? B: that's right. Give the machine a moment to process you request. Then take your money. A: these machines aren't very difficult to use. In fact, I quite like them. They are much faster than dealing with a band clerk.
