Is there a place to swipe your card on the pos machine?

The POS card reader itself can effectively achieve the positioning effect.

Generally speaking, pos machines have no built-in modules and can only be connected through the network. The signal strength is certainly not as good as that of a mobile phone, nor is it as accurate as the positioning of a mobile phone.

Why do you need positioning is because if you use a third-party pos machine, which is an interconnected POS machine, the whole process is relatively simple, from terminal transaction to acquiring architecture, and finally forwarded to UnionPay.

So this can be coded, so if the positioning is realized, the third party can naturally get your positioning, and it can also ensure that the positioning of the trading merchant and the hand-brush pos machine is exactly the same.
