cannot like that say LTA's fail, so many devices, so many different casing on their devices. and so many patterns from users that dunno where their antenna bands are. how to control that? its like peeing, so many people peeing for decades, urinal basin area always got urine stains.
You're right, there's a lot of variables that I failed to take into account when I made my post. I made that post with the assumption that the user gets everything right on his end
(knows which part of his phone to tap), and that LTA should upgrade the reader to make it more reliable and consistent when reading the cards/phones, assuming the user get everything right on his end of course.
At the end of the day, the experience of using bank card/virtual devices should be almost the same as using ezlink cards, else people will just go with what works the best.
Well, that's the point of the trial, as mentioned; to iron out the bugs.
