1. External bus of the motherboard: There are various motherboards for cash register products. The external bus bandwidth is 33MHZ, 66MHZ, 100MHZ, 133MHZ, etc. The higher the external bus bandwidth, the faster the cash register runs, and most supermarkets now accept cash. The machine needs ultra-fast running speed and speeds up the cash register. The basic selection is the motherboard with high bandwidth. 2, external interface capabilities: most of the main board of the cash register has more than 4 serial ports, one or two parallel port, cash box port, Ethernet port, keyboard port, mouse port, USB port and so on. Since the demand of commercial enterprises will change frequently, it is often necessary to expand the function of the cash register. Therefore, it is necessary to select products with many external interfaces, and some external devices also need specific interfaces. In this case, manufacturers need to customize to meet the needs of consumers. 3, CPU's main frequency, power consumption: CPU's main frequency determines the speed of the entire POS cash register product, so it should be selected according to the platform requirements of the running software. At the same time, the power consumption of the CPU should be considered. The power consumption of a normal CPU should exceed 30 watts, while the power consumption of a low-power CPU should be less than 10 watts. The CPU is an important heat source in the cash register. If the temperature is too high, the heat is not good, which may cause the cash register to crash. Therefore, you should choose a low power CPU. I hope that you don't want to ignore the four indicators on the motherboard. This is a key step in deciding whether you can purchase high quality products.

Strictly speaking, the cash register product evolved from the computer product, and further developed and realized the cash register and management functions in various commercial fields with the functions that the computer can achieve. The supermarket cash register is actually a specially customized computer. Its Design can better adapt to the complex cash register conditions of the supermarket and can run stably. Today I want to give everyone the choice of the cash register motherboard.
4, the whole machine power consumption and heat dissipation design: POS cash register use environment is relatively poor, poor ventilation, so pay attention to the overall power consumption of the cash register, try to choose low power products, this will greatly reduce the possibility of crash . At the same time, we must consider the heat dissipation design of the whole machine, especially in the high temperature zone in the south. The cash register uses a reasonable heat dissipation design, selects the top hardware, and its products run stably, bid farewell to the failure of the overheated crash.
