Now the question arises as to how does it work? A user can select the card on mobile phone application from which he wants to pay, and touch the cover on any normal card swipe machine to pay and the transaction will take place. This magnetic secure transmission technology – MST from the company LoopPay produces the changing magnetic fields over a short period of time. This is an highly trained technology that runs through an inductive loop. This in turn can then be received by the magnetic read head of the credit card reader.
