ATM skimming is the theft of card information. It occurs during legitimate transactions from ATMs.
How ATM Skimming Works
To steal your information, thieves install electronic devices called skimmers over the normal card reading slot of ATM machines. These skimmers record the data from the magnetic strip on the back of your card.
A tiny camera is often hidden near a skimmer to record your PIN as it is entered.
The thieves then use all of the information they have gathered to manufacture counterfeit cards, make purchases and withdraw funds from your accounts.
Skimming devices come in many forms and can be hard to detect. The image below illustrates how a skimming device and hidden camera can be installed on an ATM. (Actual devices may vary from this example.)
