What is skimming? How do skimmers work? How can I avoid being skimmed?

Skimming is the illegal taking and copying of bank card and credit card details. It is a form of fraud in which criminals copy the magnetic strip of a card and obtain the PIN code while a payment transaction takes place. The fraudsters then make a copy of the card. With the PIN code, they are able to withdraw cash and make payments abroad at terminals that still use the magnetic strip. Fraudsters are becoming increasingly creative.
