The advent of mobile phones has brought convenience to our lives and shortened the communication between people. It is also possible to swipe the transportation card, and to pay for things and eat with the mobile phone, and the mobile phone becomes inseparable. However, everything has advantages and disadvantages. While mobile phones bring convenience, there are also many problems. For example, mobile phones are not allowed in the examination room, and prison detention centers will also implement control over mobile phones.
