Very inconvenient. I wish more banks had the feature of Simple[1][2] where from the mobile app, you can lock and unlock your card at will. They emailed customers proactively regarding the Target breach and suggested that if you are really worried, you can leave your card in a locked state and then unlock it only when you need to swipe it.

Since they by default send a push notification on every transaction, it'd be overkill as long as you respond quickly in the even of an unauthorized one.

[1]http://www.simple.com [2]simple is fantastic for a whole host of reasons. Check them out. I'm not affiliated in any way, but have been using them as my primary bank since early on in their beta.
