Now when we go shopping, eating, and doing some beauty shopping, we will find that almost every merchant has its own cash register, and the cash registers of each merchant are not the same. Through this, you will find that the cash in the cash register market is mixed up.

In fact, the cash register is also evolved from the computer, with the functions that the computer can achieve, further research and development, to achieve cashier and management functions in various commercial areas. This shows that many people suddenly realize that it is not possible to assess the cash register by means of computer evaluation. Right, today, Xiaohuo is to teach everyone to choose the cash register through some evaluation methods of the computer.
Operators should pay attention to performance indicators when purchasing cash registers, such as the external bus of the motherboard, the external interface capability, the CPU's main frequency, power consumption, power consumption and heat dissipation design.
1. External bus of the motherboard: There are many kinds of motherboards for the 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.
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 needs of commercial enterprises will change frequently, it is often necessary to expand the cash register function, so it is necessary to select products with many external interfaces.
3, CPU's main frequency, power consumption: The CPU's main frequency determines the running 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.
4, the whole machine power consumption and heat dissipation design: POS cash registers use the environment is relatively poor, poor ventilation, so pay attention to the overall power consumption of the cash register, try to choose low-power products, which will greatly reduce the crash may. At the same time, we must consider the heat dissipation design of the whole machine, especially in the high temperature zone in the south.
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.
