Hi, Type 2 cards are thicker and will not fit into the type 1 slot.

But the guy said he couldnt tell if it was type one or two, didnt say anywhere on the package. I decided that since they have a return policy I may as well buy it and try it. Sure enough, it works just fine. What is the difference between Type 1 and Type 2? How can I tell which one is which? And what is the reason Type 2 supposedly doesnt work? Thanks! Christine
