A、The transaction lasts a long time for the machine to check data. B、The payment will be made when you enter the PIN. C、There is

M: Hello Betty, have you got two pounds? I forgot my wallet and I need a coffee. I’ve only got these pennies.
   W: Sorry, Jack. I always use my bankcard in the cafeteria.
   M: You use a card to buy coffee?
   W: Yes. It’s a tap-and-go card, so it’s quick — you don’t enter a PIN number — and everyone in the coffee queue uses them... except you.
   M: Well, I pay for things with money!
   W: There are different kinds of money. You’re still digging around in your pockets for change, Jack. I suppose you still use cheques?
   M: Yes, I do. Cheques are very useful. So help me keep up, Betty. What’s a tap-and-go card? I thought you were talking about your regular bankcard.
   W: Well, tap-and-go cards are regular bankcards but with a built-in chip and antenna. The card reader sends out a radio frequency and when you bring the card close to the reader, the antenna picks up the signal to make the payment.
   M: Hmm. This antenna business doesn’t sound secure — an antenna is used for sending or receiving radio signals. Doesn’t it mean your personal data is flying around for anyone to steal?
   W: Nothing’s flying around! At less than half a second per transaction, there’s no time for anyone to steal your cash!
   M: What if someone steals my card?
   W: Each contactless payment is limited to a certain amount — the UK’s limit is ￡30. After you’ve used your card a few times in a row, you have to enter your PIN. Whereas, if someone steals your banknotes, that’s your bad luck!
   M: OK, good points.
   W: And there is new technology coming. If getting your bankcard out seems like too much trouble, there’s a solution. For those times when not even carrying a card is convenient — at the beach or a festival for example — the fingo-pay system reads the unique maps of veins under the surface of your finger. The trick is remembering which finger you registered with.
   M: Sounds interesting.
   W: This high-tech stuff is amazing! Some day soon we won’t have to carry a wallet or a purse or anything. The veins in our finger will authenticate payments — and prove the payments are ours. I can’t wait!
   M: Hmm. But it still sounds a bit too sci-fi for my liking. I still prefer banknotes.
   W: Alright then. I have a question for you. Do you know which man’s face appears on a UK ten pound note?
   M: I only know the Queen.
   W: Yes, the Queen is on one side, but on the other side of each note is an important historical figure.
   M: Oh really? I’ve never noticed. Is it Albert Einstein?
   W: No, Einstein was German, not British.
   M: Then I’ll go for Isaac Newton. He’s a historical figure.
   W: Actually it’s Charles Darwin. Isaac Newton was on the old one pound note which is no longer used.
