Which input device
Is it possible to capture which input device was used for data entry - eg keyboard/barcode scanner/card swipe/
With most card swipe, barcode scanner gadgets, you can program a pre- or post-amble that appends text to the beginning or end of your scanned text. Program a unique character or group of characters as just such a pre or post amble and then use either calcualtion fields or a script to parse out this label to distinguish between input devices.
(You can usually program a post amble that includes a tab or enter character, so that a script is triggered at the end of each scan if you have filemaker pro 10.)
