At Lotus, they require the pin only above 1,500 baht...
But otherwise, yes, the pin should be required for all payments, never mind the amount.
What's the point of having a security pin code if it's never required?
I welcome the thought of cashless society. I can't wait for it to happen!
Move to Sweden, they are already implanting chips under peoples' skin... soon they will remove the non essential parts of their brain, and that will be heaven!
