Fast Input as Wedge, POS Hardware Profile
You use the "Fast Input as Wedge" check box to turn on detection of scanner or MSR(magnetic stripe reader). When this check box is enabled the POS will detect scanners or MSR by the speed of input.
The Fast Input Character Interval, POS Hardware Profile is used to set the time in milliseconds that can elapse between character inputs so the POS will detect the input as coming from a scanner or MSR (If the time between inputs from user exceeds the Fast Input Character Interval, POS Hardware Profile then the POS will not detect that input as coming from Wedge). This can be used to detect scanners that cannot be detected by other means.
