In the "more" category, I'm drifting towards a cashless world, which for me is cool, I noticed that Lotus had an online app, so I added it, setup was going well until it said "You need to verify your account by taking your passport to the local store". Which i did and to my surprise they knew what to do. Looks like trying to make sure scammers dont eat lol.

At Chiang Mai Immigration, nice idea, not sure if all the QR codes will work on the photo (if cropped and isolated), but maybe. Or look out for this poster at your immigration office or an immigration website.
