ATM card skimming is on the rise in the nation, and hit home in Iowa last week. Two men have been charged with using skimmer devices to capture bank account information at three locations around Des Moines.
A skimmer device fits over the ATM's card reader slot and has its own memory chip to record the information on the card as it is swiped. Skimmers secretly record bank account data when a user inserts an ATM card into the machine. Criminals then can encode the stolen data onto a blank card and use it to access the customer's bank account. Skimmers also come in different colors like the green one used in Des Moines, or in a grayish color that would look similar to an ATM, making it hard to tell it's fake. Original card readers are usually concave in shape (curving inward), while skimmers are more convex (curving outward).
The use of keypad overlays placed directly on top of the factory-installed keypad is a relatively new technique that takes the place of a concealed camera. Instead of visually recording users punching in PINs, circuitry inside the phony keypad stores the actual keystrokes.
