Teao,
There are three types of scanner we use. We scan 1-D and 2-D barcodes. 2-D Barcodes contain multiple fields of data. Scanner number one is a keybord wedge. It works as if you are typing. Scanner number two is connected to a serial port. We have code that will take the incoming data and processes it and puts it in the proper fields. Scanner number three is connected to a USB port. We have code that also processes the incoming data. In the 1-D barcodes we have put a special character in the first position of the barcode that is detected by the validate procedure to make sure it is put in the correct field.
