Preventing Credit Card Data Theft



A good way to ensure the security of our card is to prevent both data theft and theft of the physical credit card itself.

When we talk about credit card theft, it is natural that the first thought that comes to mind is that of physical card theft, but curiously, within the growth of this type of crime, theft is by far not the one that has increased the most. The theft of credit card data has grown spectacularly and it is necessary to know all possible resources to prevent it.

The data are overwhelming: at the beginning of this century, credit card fraud increased by 80% compared to the 90s of the last century, to continue increasing year after year and become one of the crimes with the highest growth rate globally, something that of course our country is no stranger to.

How can my card data be stolen?

Unfortunately, there are many ways in which credit card data can fall into the hands of criminals, the most common of which could be as follows

  • Fake readers installed in ATMs or payment systems that duplicate the card data.
  • Use of the card in unsecured sites
  • Access to sensitive information (account data, card data and PINs) through the network or various media

Of the three, the most relevant is the second one, but we should not overlook other issues such as security breaches on trusted sites, which sometimes we do not give importance beyond the fact that they are news, but which can nevertheless lead to a huge loss of data to criminals.

Preventing credit card data theft beforehand

Just as the physical theft of a card is more complex to prevent, although there are of course security measures, in the face of card data theft there are sufficient preventive measures that, although they do not prevent 100% of our exposure to this crime, they greatly reduce the chances of it happening to us.

  • When contracting, take the card from the bank itself, do not ask for it at home.
  • Sign the card as soon as you receive it, this signature is usually not made and nevertheless it is important.
  • Use PIN numbers not related to issues such as family ages, special dates, names, family acronyms…
  • Do not use your main card for online purchases, there are simple alternatives such as virtual cards or secure payment services.
  • Check ATMs if they give you a bad feeling, tell the bank immediately if you find something strange. Generally the machines that try to duplicate the cards do not have the same mechanical behavior when swallowing the plastic. In the same way, if you find cameras or suspect them where they should not be, notify the entity.
  • If you make offline payments with your card do not let it out of your sight, claim if necessary that the payment is made in front of you.
  • It is not advisable to make payments via telephone with the cards, it is better to use virtual cards, in any case, if made, only do it with reliable sites where immediately give us a copy via mail of the payment made.

Automatically a block is generated on the card and the access to our resources, it is important, in case future claims should be made, to obtain some proof or note of the moment in which the fact has been communicated.

Secondly, it is necessary to make the pertinent report to the authorities, which should provide as much information as we can add.
