I think you are getting confused between card information vs transaction information. I bet Target's card swipe terminal is secure enough as Target doesn't own it. It's owned by NCR or some other company who must be implementing encryption. Apple Pay is just another variant of that.We live in a time when everyone should expect to get hacked at some point, I get that. Knowing that however companies should be taking steps to mitigate damages when they are hacked. There should be monitoring and segmenting to identify attacks and prevent them from quickly spreading. Target taking over two weeks to know they had been penetrated and having the infection spread throughout their entire US network is unacceptable. I'd expect they've learned from that very expensive lesson but I'm still inclined to use systems with one time tokens and data stored uniquely on my own device. That's the epitome of segmentation and means I don't have to care whether any retailer has been hacked provided - unlike Target and Walmart - I was able to use a truly secure payment mechanism.
Target hack exposed all the target issued RED Card information.. not other card information.. unless people stored their card information using Target online web site.
