I am writing an application where I need to accept information from a mag swipe keyboard edge. I am running into concerns in regards to the wedge's print speed. Any lag in the application, even at input, is very important.
I can not seem to find an answer to this question:
What is the main bottleneck for a mag stripe reader's print speed (keyboard wedge specific via usb or usb slave)?
I have noticed that the print speed differs from machine to machine. I want to say that it is either the usb port or the RAM on the device but I unfortunately don't know enough about the hardware end of things to come to a conclusion. Furthermore might it be the operating system or card reader? I know the reader itself has a print speed but that does not explain the fluctuation.
Anyone know as to what it might be?
