The mobile phone is set to become one of the central technologies of the 21st century. Within a few years, the mobile phone will(S1)evolve into a multi-functional communicator capable of(S2)transmitting and receiving not only sound, but also video, still images, data and text. A whole new era of personal(S3)communications is on the way.
    Thanks in part to the growth of(S4)wireless networks, the telephone is converging with the personal computer and the television. Soon light-weight phones(S5)outfitted with high-resolution screens will be(S6)connected to satellites enabling people to talk, send and receive e-mail, or take part in video(S7)conferences anytime, anywhere. These phones might also absorb many of the(S8)key functions of the desktop computer.(S9)Mobile devices are expected to be ideal for some of the personalized services that are becoming available via the Internet, such as trading stocks, gambling, shopping and buying theater and airline tickets.
     (S10)The telecommunications revolution is already taking shape around the globe, which really helps people a lot. In Europe, mobile phones are already being used for electronic commerce. Most phones contain a subscriber identification module or SIM card to identify a user to the phone network. But the card could also facilitate limited financial transactions. Deutsche Bank and Nokia, for example, are working together to develop mobile banking services. Another approach is to add a slot to mobile phones for a second smart card designed for mobile e-commerce.(S11)These cards could be used to make payments over the Internet or to pay for things like public transportation, movie tickets or drinks at a bar.
