The Two-Dimensional Bar Code Application in Book Management

Two-dimensional bar code is one of the most basic and key technologies to achieve the process of identifying information technology for the Internet of things. This paper focuses on book management based on two-dimensional bar code through Visual Basic.NET and SQL Server databases. It can achieve anti-counterfeiting, automatic book information entry, reader identification and library lending management. It can also achieve a seamless transition from the existing one-dimensional bar code ISBN to two-dimensional bar code ISBN.
