Cyber Credit

''Backed by the Cyber bank on Shadowside, this credit card has a very low circulation, carried usually by members of the trading underworld. It is commonly used by arms merchants.''

You can use the Cyber Credit to purchase the Mass Converter on Starport. Get the Cyber Credit by giving the Android on Impremi Homeworld a Uni-Lock. Note that this is the only way to get the Cyber Credit from the Android: you will not get the Cyber Credit by killing him.
