FTDI stands for Future Technology Devices International Ltd.

Therefore, the cable with the Prolific chip now lives at Ox Mountain (the local landfill) while the cable with the FTDI chip will be used to connect to a barcode reader. My anecdotal evidence is that the cable with the Prolific chip paired with the Prolific driver from the Prolific website gave me the garbled data, while the FTDI cable with no extra effort has been working great. The cable is made by a different manufacturer, but the product description usually tells you which “chipset” is embedded in the cable. These companies design the silicone that lives inside a small black box that lives on a printed circuit board that lives inside your converter cable.
