It's not 'A Scanning Device' ! It's a Scamming device !! ie a False front over the original ATM front with some cute software running and a Card skimming device.... Once you enter your card into the fake front the magnetic strip is read into the device, this is where all your data is kept in 3 layers.... Once this data has been collected and your Pin has been snatched all that has to be done is a blank card (same as a mobile topup swipe card etc) is then programmed with your stolen details from your original Magnetic strip...

) Either until your hacked account is reported or your account has been emptied....
Chinese card readers and programmers have been available for years now and for an outlay of $100, you can never be safe at all now because of this, Dubious restaurants have been using these devices for years, when paying for a meal or shopping anywhere, especially abroad.... NEVER LET YOUR CARD OUT OF YOUR SIGHT !
When Chip and Pin came in, in 2003 it was meant to solve a lot of these problems, this was meant to phase out the hackable magnetic strip, but the magnetic strip have remained basically as a backup and incase the chip cannot be read...
At the tail end of 2010 Cambridge Uni hacked the Chip and Pin security and released the software to do this as open source, no bank card is 100% same now... If your worried about your cash, keep it under your bed, for all the interest you get in the bank anyway
You really have to be aware were you are actually sticking your card into nowadays....
But in all honesty how people cannot distinguish between a fake Atm cover and a real ATM front is beyond me...
Maybe because i've been in the Technology game all my days etc I notice things that are out of place...
Be alert.... and stay safe.... (Goes with your Computer too....)
