| In the Pinellas County of Florida, America, when they get on and off any of the school buses, students will have to show their special pass ─ finger. These school buses will be equipped with new high-tech facilities — digital fingerprint scanners and GPS, satellite locators — to track drivers and their young passengers. The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a network of 24 satellites and their ground stations. In fact, it's like giving every square meter on the planet a unique address. These days GPS is finding its way into cars, boats, planes, construction equipment, movie making gear, farm machinery, even laptop computers. Thus, the system will help ensure that the kids get on and off the right buses, as well as to monitor drivers' routes for efficiency and safety. The child's fingerprint will be registered into an electronic database using an electronic scanner. When they board, children press their finger into a reader. If the computer doesn't find a matching code for a child's print, the system alerts the driver that the child most likely doesn't belong on that particular bus route. 百灵编辑：茂军  | |
