Japan will start an aggressive push to market abroad its mobile technology, especially the nation's popular "wallet phone ," a government official said Tuesday. Although Japan boasts some of the most sophisticated cell phones in the world, the nation has failed to make its handsets, wireless technology and mobile services hits outside of Japan. Among the wireless innovations Japan hopes to peddle is the wallet phone. The technology relies on a tiny computer chip, embedded in each cell phone, which communicates with a reader-device at stores, train stations and vending machines for cashless payments. This tiny computer chip was developed by Japanese electronics and entertainment company Sony Corporation. |
