Wun the electromagnetic wave from the phone interfere when you
tap? As in the mrt tapping plate produces error?
I saw many ppl tapping their wallet (with their ezlink card
inside) and the plate shows error / not able to detect. No
prob when they took out the card and scan it separately
It's the ammount of other cards inside ur wallet tat's
disrupting the scaning... The scanner cant scan thru...
However i dunno if the scanner has an adverse effect on ur phone
after long duration of usage like VK's...
