Many licensed software packages require keys (dongles) in order to operate. However, many of today's laptops do not have built-in parallel ports. A PCMCIA card such as Quatech's SPP-100 that functions exactly like a native bi-directional parallel port solves this problem and enables the software keys to be used.
For example, one Quatech customer uses Quatech's SPP-100 EPP parallel PCMCIA to run embroidery software on a Babylock electronic sewing machine. The software uses a security "dongle" that must be attached to a bi-directional parallel port provided by our card.
Interesting note: USB to parallel adapters often cannot be used for this purpose because they do not provide full bi-directional communication, they are simply printer ports.
