What will they come up with next?

In Tokyo, Japan cell phones have a whole new use. Some 10 million Japanese commuters use smart cards embedded within their cell phones so that they can pass through subway station gates and not have the hassle of dealing with coins or fare cards. This newly invented chip for cell phones will facilitate traffic in this highly overpopulated city.The Suica electronic train-fare system uses Sony's IC chip technology called FeliCa, which is also used in other kinds of electronic cash cards. As the technology becomes more popular, users will also be able to use their Suica-compatible cell phones to pay at some restaurants, convenience stores and shops. This technology will not be out in the United States for atleast another couple years. But when this chip does come out in the U.S., life anywhere, but especially in major cities such as New York and LA, will be less hechtic. These two cities will be the true test as this technology enters U.S. economy. Wow, cells phones have the potential and capability to do anything!
