 An additional advantage of this architecture was that the "InternetCash Payment Window" could be used to securely accept any type of payment, including credit cards (much like 3-D Secure), debit cards and checks, and not just its own pre-paid cards.In fact, efforts were made by its founders to enable American Express's "blue" chip cards and regular debit cards to be used online, but after the Internet crash many of the companies involved put these projects on hold.In addition to building its own secure Internet-based payment network, InternetCash utilized hardware encryption devices from nCipher (acquired by Thales on July 11, 2008) combined with custom code for generating its card numbers.
