Historical Development Of Cash Register

1. Class I cash register: 8-15 Department categories, no more than 500 single commodity management, and daily business statistics report. It refers to a cash register that can only be used by a single machine and can not be networked. It can manage several to dozens of departments and can manage a small number of commodity items. This type of cash register has many varieties, basically the same performance and relatively low price. The cash register processing program is fixed in the cash register and cannot be changed. The cash register can only provide simple statistical reports. Because the data storage area is small, the data can not be kept indefinitely and needs to be cleared regularly.

2. Class II cash register: There are 30-99 Department classifications and 500-7000 single commodity management. It has abundant daily and monthly turnover statistics reports and can be connected with computers. It can operate on a single machine or be networked. It can manage several to dozens of departments, manage a certain number of commodity items, and connect simple peripherals, such as the cash register of bar code scanning equipment. There are many varieties of this type of cash register, and there are some differences in price and performance. Individual cash registers can print Chinese characters. The processing program of the cash register is fixed in the cash register and cannot be changed. The collection statistics report can be obtained from both the cash register and the networked computer. The cash register and the computer use RS232 port for networking communication.

3. Three types of cash register: POS machine, which is composed of 486 or above computer host, 9-inch display, cash box, high-speed printer, standard keyboard, etc., and has standard computer interface. Also known as PC-Base cash register, its hardware foundation is the basic part of general-purpose computer. It adopts international standards and has high standardized procedures during production. Because the hardware can well support the system software and the application software to meet various needs, especially the relatively mature Chinese character system can be used to realize the input, display and printing of Chinese characters in the national standard font. The third type of cash register has not only the general interface of the computer, which can be connected to a variety of networks, but also the special interface suitable for the business environment, such as the peripheral interface of the magnetic card reader, the cassette and the bar code reader. It also has a special keyboard for the business environment, and each key can be redefined. Due to the complex application environment, its anti-interference capability requirements and durability are much higher than those of general-purpose computers.
