Hello there ,
I was using the QR generator you mentioned on your page here: thenationhotnews.blogspot.com/2011/08/
(sorry for the email in English, it's easier for me to read than write in Thai).
I really enjoyed working with quickmark.com.tw in the past, but I recently found a new one that is more visually appealing, has a lot of customization options, and is totally free: https://www.websiteplanet.com/th/webtools/free-qr-code-generator/
It allows you to create your own personalized QR code (you can choose the color, add a frame and even add the logo of your company and/or social networks), which I think is awesome.
I believe that it would be a great addition to your page, I'm sure your readers will appreciate it.
In hope I helped back,
Anna
