In the months since [the hack was found], Target adopted a faster timeline for switching to more secure chip-based credit and debit cards, and the payment terminals that accept them. As part of the $100 million effort, Target announced last week that it all of its store-branded cards would be reissued as MasterCard chip-and-pin cards in 2015.
This will only help customers who have such cards, which is... visitors from Europe? Anyone else? A more valuable feature for the new terminals would be code signing for firmware updates.
