This video is from a newcast from about a year ago. I'm not sure if they have gotten past this huge security hole or not, but it's worth checking out this 6 min vid (in my opinion)
Ya.. Heard of this month ago.. Big scare for sure.. I guess those Blink guys didn't think of criminals when they came up with that Idea..
My cards don't have that but there is always someone trying to scam you out of your money.
Best to use a lead shielded card holder if you want to be somewhat safer..
It's simple to be wise.. Just think of something stupid to say.. And don't say it...
