AI Technical Summary

Problems solved by technology

[0005] However, the identification information of the traditional paper admission notice is printed and stored, and its information accuracy, security, and uniqueness are poor, and the information carrying capacity is small. Limited by the paper carrier, it is difficult to fully reflect the architectural style of the school. , Humanities, history and teaching characteristics, and insufficient artistic atmosphere and sense of technology, unable to meet the enrollment needs of the new era, paper admission notices are easily damaged, lost, inconvenient to carry, do not have information interaction functions, poor security and practicability
