Oberthur Card Systems has a card designed for transit use with 3DES, according to their datasheet (registration required, http://www.oberthurcs.com/get_downloadsection_file.aspx?id=43&otherid=95&typ eid=5) it's certainly fast enough.
Interestingly, they also make the card that's failed so spectacularly here...

Not to defend the designers in any way or fashion, but I'd like to ask, How much security can you put into a plastic card, the size of a credit card, that has to perform its function in a secure manner, all in under 2 seconds (in under 1 second in parts of Asia)? And it has to do this while receiving its power via the electromagnetic field being generated by the reader.
