Once the exclusive domain of executives with expense accounts, mobile phones are set to become one of the central technologies of the 21st century. (46)
Within a few years, the mobile phone will evolve from a voice-only device to a multi-functional communicator capable of transmitting and receiving not only sound, but video, still images, data and text.
A whole new era of personal communication is on the way.
Thanks in part to the growth of wireless networks, the telephone is converging with the personal computer and the television. (47)
Soon light-weight phones outfitted with high-resolution screens—which can be embedded in everything from wristwatches to palm-held units will be connected to series of low orbit satellites enabling people to talk, send and receive E-mail, or take part in video conferences anytime, anywhere.
These phones might also absorb many of the key functions of the desktop computer. Mobile devices are expected to be ideal for some of the new personalized services that are becoming available via the Internet.
The communications revolution is already taking shape around the globe. In Europe, mall-scale trials are under way using mobile phones for electronic commerce. For example, most phones contain a subscriber identification module (SIM) card that serves primarily to identify a user to the phone network. Some manufacturers plan to upgrade the SIM card to an all-in-one personal identification and credit card. Another approach is to add a slot to mobile phones for a second smart card designed specifically for mobile ecommerce. (48)
These cards could be used to make payments over the Internet or removed from the phone for use in point-of-sale terminals to pay for things like public transportation, movie tickets or a round of drinks at the bar.
In France, Motorola is currently testing a dual slot phone, the Star TACD, in a trial with France Telecom while in Finland Nokia is testing a phone that uses a special plug in reader for a tiny smart card. Siemens is pursuing a different approach. (49)
Since it is not very clear whether it’s best to do everything with a single device, Siemens is developing dual slot phones and Einstein, a device equipped with a smart card reader and keypad that can be linked to the phone via infrared wireless technology.
(50)
For those who want to, though, it will be possible to receive almost all forms of electronic communication through a single device, most likely a three-in-one phone that serves as a cordless at home, a cell phone on the road and an intercom at work.
"The mobile phone will become increasingly multifunctional", says Burghardt Schallenherger, vice president for technology and innovation at Siemens Information and Consumer Products.
