Nowadays, more and more people are addicted to playing on their cell phone when riding transit and missing the station. Similarly, on a crowded subway, passengers can't hear or see the site information. This design allows every passenger to easily see the site information, and the handle can vibrate to remind passengers to prepare to get off. The travel information can be input into the app in advance, which makes it more convenient for passengers to log in to the handle system through their fingerprint. In this way, passengers can avoid cumbersome methods to log in to the account, and it also ensures traffic safety.
