Case study of explosion-proof lithium batteries for handheld POS machines

POS (Point of Sale) is a multifunctional terminal. It can be installed at designated merchants and credit card receiving locations, connected to computers, and automatically transferred electronic funds through the network. It has functions such as supporting consumption, pre authorization, balance inquiry, and fund transfer, which are safe, fast, and reliable. The POS system was first applied in the retail industry and gradually promoted to other service industries, such as finance and hotels. The scope of use of POS systems has also expanded from enterprises to the entire supply chain.
