Completed text: Have your phone run out of battery when you don’t have a charger? This has happened to many of us. In China, this isn’t a problem on their high-tech trains – they have introduced wireless charging, so you can charge your phone while you are travelling; they have used this technology for the last two years, and it’s very popular. Have you ever forgotten your train ticket? In Japan, they have developed a new system of tickets so that a camera ‘reads’ your face and you don’t need to carry a ticket. They have been testing the new system since the end of 2019 and hope it will be ready to use to all train stations soon.
