Skimming is an act of stealing information through the magnetic strip on the cards that are used in ATMs and merchant establishments. Fraudsters collect information from a credit/debit/ATM card by reading the magnetic strip on the reverse of the card. For doing this, they conceal a small device in the card slot of ATM's or merchant payment terminals. This 'skimmer' scans the card details and stores its information. A tiny strategically positioned camera may also be used to capture the PIN. Skimming can occur in ATMs, restaurants, shops or other locations.
