New technologies and ideas are continually emerging for using this device to make daily life more convenient. Parents keep track of their children using GPS phones, while the trains are full of people emailing, sending text messages or browsing the Internet on their phones. Mobile phones can be used as electronic wallets for e-money, accepted by many stores, public transport and even vending machines in Japan. They are even spurring new cultural developments - people don't just read comics and view movies on their phones, novelists are now first publishing their work on-line. And Japanese phone design is also winning them a place in museum collections.
