As a student, I often lose my student card, which causes me a lot of trouble, such as shopping in the school supermarket or printing in the school. The school for the replacement of the student card also needs to charge, so this is a very troublesome thing. If you can have a smart student card, it will be much more convenient. The smart student card can be added to the mobile phone wallet, the mobile phone is often carried by people, which can prevent the loss to a large extent. Meanwhile, new functions are added, such as GPS buses, real-time updated schedules, and school maps, which make it more convenient for us to use the student card.
