Magnetic tickets are expected to continue to be used for mid- to long-distance routes, such as on Shinkansen. When passengers insert magnetic tickets into automatic gates, departure stations and other information stored in the magnetically coated black portion on their back are read while the tickets are carried forward by belts and rollers. The companies said magnetic tickets often get jammed inside automatic gates and that the magnetic layer needs to be removed before recycling. Today, many passengers carry JR East's Suica and other smart cards. Paper tickets are used for less than 10 percent of train rides in the Kanto region, the companies said.
