Commercial electronic cash register is the product of the development of microelectronic technology and the combination of modern commodity circulation management concepts and technological development, while commercial electronic cash register is one of the basic electronic devices essential for modern and automated business management. The earliest cash register in the world was made in 1879 by the American brothers Janmins Liddy and John Liddy. Its function is only to achieve business record memorization and supervise the employer's misconduct. In the late 1960s, with the rapid development of electronic technology, Japan took the lead in the development of an electronic cash register (ECR). The invention of the electronic cash register has an epoch-making significance, and its technical performance and commercial functions far exceed the prototype of institutional cash. The cash register has the characteristics of intelligent and networked multi-function, and has become an effective tool and means for labor management, accounting management and commodity management in commercial sales. By the mid-eighties, a powerful commercial-specific terminal system (POS) was produced and became the third-generation cash register. The biggest difference between POS and ECR is that it has the characteristics of direct and immediate accounting, and has strong online real-time processing capabilities. POS integrates computer hardware and software to form an intelligent, commercial workstation that can work independently or in a networked environment.
