问题                         NO CASH, NO PROBLEM

    As technology continues to develop, people are changing the way they pay for things. Many of us have a cash card or a credit card, but more and more people carry a cashless card—a computerized "smart card. " These lucky people never have to look for money, or carry a-round a heavy wallet full of coins. With these cards we are one step closer to a more convenient and cashless society. The idea behind cashless cards is to get rid of small change and to save time.
    Many American and British students use these cards to buy food or drinks at college cafeterias and even to ride buses. These cards also act as ID cards. Students use the cards to access buildings and computer files, or check out books from the library. College cafeteria staff say the cards have reduced waiting time at checkouts on campus. Users can put money from their bank accounts onto smart cards at special machines on or around campus.
    There is one big problem with smart cards. If an owner loses his or her smart card, the cash that is stored on it can be used by whoever finds it. However, to protect the user, most cards have the owner’s photograph on them.
