Merchants might. Current credit-card processing terminals are increadibly overpriced for what you get. $100.00 plus the price of an inexpensive PC, plus proprietary software isn't too far of the mark, in comparison. # I agree with Perry. Hardware encryption does add a layer of security # not normally found in software, but it is hardware. I've been a fan of unrelated encryption at each layer of the 7 (5, 4, whatever) layers, lateley. In military/financial terms, the question of "who has access to what" and "needs to know what" at different levels of the protocol stack make a big difference. Network guys should be able to perform traffic analysis, application guys should be able to debug application-specific traffic, but not visce versca. # Shoot, I don't even have a 28.8 modem yet, why would I want a black # box that supposedly does something with my Credit Cards? If you think "Not _my_ credit cards, but my _customers'_...", then it starts to make sense. -- Steve@AZTech.Net
