Credit cards are usually hacked through a process of cloning which is known as "skimming". This is where the details of your credit card are captured using a device, known as a skimmer, attached to an actual transaction - eg. at a shop or cash machine.
Unfortunately these sort of instances are on the rise, and card companies have not yet found a way to prevent this occurring. But there are precautions you can take to prevent this happening such as:
- Do not carry or use more cards than you really need
- Ask to have your card replaced every once in a while
- Always check your statements and online banking to ensure there are no fraudulent transactions that you do not recognise.
