Are these that unusual? It seems like I hear about cops finding these relatively frequently in the local news wherever I am. I haven't used an ATM in years without checking it out first and covering my hand so a camera can't get the PIN.
At least in the UK it's common enough that there are usually notices on the machine to warn you of suspicious devices attached to it and phone number to call...
Yeah but then most online places are going to require the extended information number, or a street address and other info which isn't on the card's magnetic stripe.
I suppose these guys could be setting up their own merchant accounts and finding providers who don't require this info. Or even creating fake cards and then using those. Both of those options seem a bit riskier to me...
I moved to Toronto last year. One thing that I still can't wrap my head around is that a huge number of ATMs are open to the street. I always feel VERY uncomfortable getting money from them.
