Train Conductors and QR Code Readers

This is a typical conductor on a Thai train. Except for one thing. These days, train tickets have QR codes. So, instead of carrying a ticket punch for checking tickets, he is carrying a QR Code scanner. After scanning, his device will tell him things like train and seat numbers. As you need to show your ID card or passport when buying tickets, it’s not a good idea to post your ticket on social media as people will be able to see your personal details like this conductor can.
