Has anyone had luck calling MagneticStripeReader.GetDefaultAsync()

0.00/5 (No votes)

I am writing a Windows Runtime ("Metro") application that needs to read from a USB magnetic stripe reader. As per everything I've read, I've tried to use MagneticStripeReader.GetDefaultAsync() to find my reader. This always returns a null. Then, I tried using MagneticStripeReader.FromIdAsync(deviceId), where the deviceId is the value I've obtained from Device Manager. This also returns a null. I know the reader is functional, as I have used it with a "desktop" app I wrote a while back. Does anyone have any pointers as to how to get these API calls to work?

Are you sure you have allowed access to the reader? I think the GetDefaultAsync will return null rather than chucking an exception on access rights issues.

Fredrik, thanks for your reply. I had already edited the manifest to add a DeviceCapability with a value of "pointOfSale" before posting my question. Is that what you mean?
