While credit and debit cards make life more convenient on the go, there have been a number of skimming incidents at credit unions around the country, including at the $1.023 billion Northeast Credit Union in Portsmouth, N.H.

"We're seeing more and more of this type of fraud, and credit unions need to be more aware where they place their ATM machines and their cameras," said John Bennett, a spokesperson for the Portsmouth, N.H. police department. "Nothing seems to be able to stop these types of thieves, and you have to be very aware when you are using an ATM these days."

It's alarming how easy it is to install a credit card skimmer, which captures information from a card swiped at a point-of-sale system. A recent video released by the Miami Beach Police and posted to CBS Miami's Facebook page shows two men attaching a skimmer to a gas station payment terminal. In the video, one man distracts the store clerk with polite conversation and a request for some items behind the counter. While the clerk gets the merchandise, a second man slips the skimmer over the POS system. The device is installed within a matter of seconds.
