"Paperless" ticket is also called electronic ticket. In the demonstration of single apricot blossom, we can see that the specific mode of operation is to derive the two-dimensional code from the mobile phone APP of 12306, which can be smoothly opened and passed at the ticket-checking gate. For people who don't use smartphones, there's also a way to brush their ID cards, but paper tickets can't go back anyway.
What about reimbursement? After purchasing electronic tickets, you can print reimbursement vouchers in the window only by virtue of your ID card.
Others may say that I've already used a paperless ticket.
Yes, you're right! At present, the number of high-speed trains going north to Guangzhou and Shenzhen and between the main second-tier cities in China has basically realized ID card brushing.
However, most of the other second-tier cities and cities below the prefecture level and counties still do not support "paperless" ride. When people take the bus, they still need to exchange paper tickets to get in.
But from now on, no matter where you are in China, forgetting paper tickets, it has become a reality that "one machine in hand, the world has me".
