Traditional Pos machine

Traditional Pos machines usually need to be connected to power supply and telephone line before they can be used. Its main advantages are high stability and good connection state, even where the signal is weak. In addition, the traditional Pos machine is relatively safe, because it needs to connect to the telephone network and pass the bank authentication to complete the transaction.

However, because the traditional Pos machine needs to be connected with a telephone line to operate, it cannot meet the demand of modern consumers for mobile payment, and its maintenance cost is also relatively high.
