This is a good, quick article from Wired in response to some recent news stories that the wireless carriers were trying to do an end-around on the credit card companies.  Some one finally got around to doing some actual investigation on what the carriers were doing and it’s not an end-around, Discover’s highly involved.

The article also talks about why the major card brands work and attempts at breaking the system and introducing a new model for credit cards (none of which have yet worked)…  Not really a security article, but one that is highly relevant given the focus on payment security.
