I just made my 1st purchase with Samsung Pay in Mr DIY, lol.
This is a small branch, their machine not even support pay wave, when I say i wanna pay with my phone,
the cashier said "sorry sir, no pay wave here, card OK".
Then I insist and told her just enter the amount into the machine 1st, then I put my phone near to the card slot, Beep!
Voila~ done! The cashier staring at my phone during waiting the slip printing, LOL.
I think as long as MST tech implemented, i think Samsung Pay will go on and might getting popular in future.
i failed twice and some members at here told that some merchants already disabled the MST that's why not working
