What is the contents of the qr-code? qr-code มีเนื้อหาอะไรบ้าง?
Does it contain a link to some website? มันมีลิงค์ไปยังบางเว็บไซต์หรือไม่?

Scanning qrcode just gets a link or url, it will guide someone to pay for something, you can check the payment if it happened.

Who is the charging pile provider? if you did the payment, he also received the payment notice and he would turn it on by IOT.
