Question

Why do some receipts in some shops in Thailand indicate "authorized tourist"?

Example from Tops supermarket in Bangkok:

Answer 1

That looks like a The 1 card, but with a generic number and name. Most likely this is because you didn't actually present one of these cards when you made your purchase. Using a generic number like this, you might get some privileges such as discounts on your purchase, but not any points as you aren't in the program. It appears you got a discount of 11 baht on whatever you purchased.
