keycard, lock your mac with your phone


keycard is a simple yet very practical app that allows you to lock you mac by simply walking away.Well, I mean You and your smartphone walking away. As simple as that.

no doubt this is very useful but the maker seems to overestimate the value of the app, for it costs an arm, really: 6,99$. I also fell concerned about battery usage, because I don’t own an Iphone 4s and over, which have bluetooth 4.0. Anyway, seems like fun.
