At present, there are many manufacturers of POS products sold in China, the quality is uneven, and the price is huge. The main reason for the price gap is the large cost gap. Here is an analysis of how the cost of low-cost POS is saved:
1. Use outdated materials or even recycled old materials
The use of old materials and outdated materials is the main trick used by low-cost POS. For example, LCD screens use used old screens, CPUs on the motherboards and chipsets (Intel), granules on memory sticks, etc., and there are a large number of refurbished small companies in Shenzhen and other regions. And making these recycling quantities into new motherboards, memory sticks, etc., is difficult to identify for the general staff. However, the reliability of these recycled materials cannot be guaranteed.
2, equipment cut corners
Many POS machines will have 3C certifications for external use. In fact, the products sold are in the form of stealing beams and columns, which have not met the requirements of national 3C certification. For information products, 3C certification mainly includes electrical safety (GB9254) and EMC (GB17618). At present, many POS power supplies sold are in line with 3C certification, and there are serious security risks. To meet the requirements of EMC, the product must have good metal shielding, and a large number of DIY and bottom price POS adopt ABS plastic shell structure, which can not meet this requirement, and of course save a lot of costs.
3. The design and selection of low-priced POS products are not suitable
POS machine use environment, pos machine use environment is relatively harsh, low temperature and anti-static is a very important indicator, generally to meet the requirements of minus 20 degrees or 45 degrees, and can resist electrostatic shocks above 8000V, this is also a POS machine One of the main differences with ordinary PCs. The design of low-cost POS is seriously inadequate in this respect, even worse than ordinary computers. Of course, this also saves a lot of cost for low-cost POS.
