Are you looking for a scale that's run at the POS position, or are you looking to read a barcode placed on a product that includes weight and price data? A number of companies product scales that are accessible as serial devices; you'd have to write code that read the current weight from the scale on demand, not difficult to do, but in almost all cases, the code to do this would depend on the product being used. I'd suggest looking intoi a scale that uses a serial port as an interface, preferably one that comes with an ActiveX control from the vendor that does the work of communicating with the scale, or a standard serial interface that's well documented and compatible with the MSCOMM32 serial control that comes with VFP.

If you're reading a barcode, I'd try to get what's known as a wedge scanner - it acts as if information were being typed into the keyboard as text - you would read a field populated from the scanned barcode on the item and parse it - this also gives you a way to handle situations where the barcode can't be read; the information could be keyed into the same fiedl from the keyboard and processed as if it were read from the barcode.

In both cases, Hallogram sells barcode and scale products that work with VFP www.hallogram.com is at least one site that sells hardware and software for the VFP developer.
