A wired network connects a desktop POS machine to a network via an Ethernet cable. This setup requires specific wiring and equipment, such as a router.
Advantages: It is not affected by external interference, is relatively stable, has a dedicated connection, is not susceptible to illegal external access, and reduces the risk of poisoning and data leakage.
Disadvantages: Cables are required, which may be troublesome.
A wireless network, such as Wi-Fi, enables a desktop POS machine to connect to the network without physical cables. It relies on a wireless access point (AP) or router to provide signal coverage within a certain range.
Advantages: No wiring is required, it is relatively flexible, and the deployment is simple. As long as you are covered by the wireless network, you can work anytime and anywhere.
Disadvantages: It is susceptible to interference, the connection strength may be blocked by walls or other buildings, and compared with wired networks, it is less secure and susceptible to illegal intrusion.
