I am trying to create a vi that acts like a credit card scanner similar to the ones in Wal-Mart or other stores. I am new to labview and could use some direction. Can anyone help? Tim Scott
Seriously, buy a card reader. These devices must have an interface of some kind (serial, USB, etc.) that you'll can program with LabVIEW I/O functions. If the device, has a well done driver, then using the device might be as simple as calling a DLL or an ActiveX component.
We can't help you much more if you don't provide more information about the interface of the device.
