     They like using the Internet. They have lots of pocket money to spend. And they spend a higher proportion

of it online than the rest of us. Teenagers are just the sort of people an online seller is interested in, and the

things they want to buy-games, CDs and clothing-are easily sold on the Web.

     But paying online is a tricky business for consumers who are too young to own credit cards. Most have to

use a parent's card. They want a facility that allows them to spend money.

     That may come sooner than they think: new ways to take pocket money into cyber (网络的) space are

coming out rapidly on both sides of the Atlantic. If successful, these products could stimulate online sales.

     In general, teenagers spend huge amounts: $153bn (billion) in the US last year and£20bn annually in the

UK. Most teenagers have access to the Internet at home or at school-88 percent in the US,69 percent in the UK.

According to Jupiter Research, one in eight of those with Internet access has bought something online- mainly

CDs and books.

     In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory

for them and their children. Pressing parents to spend online is less productive than pressing on the high street.

They're more likely to ask "Why?" if you ask to spend some money online.

     One way to help teenagers change notes and coins into cybercash is through prepaid cards such as Internet

Cash in the US and Smart Cards in the UK. Similar to those for pay-as-you-go mobile telephones, they are sold

in amounts such as£20 or $50 with a concealed 14-digit number that can be used to load the cash into an

online account.
