In April of this year, the Tokyo Metro in Japan began testing a set of RFID technology interactive map system, in order to let passengers get more help. Mobile phone users that support Felica RFID technology can also press a button on the map to activate a Felica sensor, move the phone close to the screen, and download the location coordinates to their phone. When returning to the ground, the user can use mobile phone mapping technology to draw the route to the destination.
For example, there are countless restaurants, cafes, bars, and small shops in the Ginza area. In particular, the Ginza subway station has 32 exits and a total of 3 subway lines intersect here. Therefore, travelers who are not familiar with this area often find it difficult to find a destination. This kind of area needs to adopt this kind of high-tech map system very much.
Currently, the Ginza station uses two 47-inch LCD flat screens to display the map of the area. There are buttons on the screen, and passengers can highlight some frequently visited places, such as banks, ATMs, convenience stores, and post offices through the buttons. When a button is pressed, all the locations of the place corresponding to the button are displayed on the map, and are marked with icons. The user touches one of the icons, and the map can draw the shortest route from that place to the destination.
For other locations, passengers can query by simply entering the address. Since this map system only covers local areas, users only need to enter two or three numbers representing specific areas and buildings, and the system can display the route.
