Since the 1970s, due to the rapid development of science and technology, especially the use of computers, the scope of use of bank cards has continued to expand. It not only reduces the circulation of cash and checks, but also breaks through the limitations of time and space, causing fundamental changes in banking business. With the application of the bank card automatic settlement system, the arrival of a "checkless, cashless society" will soon become a reality.

The 20-year development history of China's bank card industry can be roughly divided into four stages:

The period from 1985 to the early 1990s is the primary stage.
