Basic rules to put into practice

More and more people are abandoning the idea of ​​having cash in their pockets, and largely preferring to pay with credit or debit cards. So much so that this trend has not gone unnoticed in the eyes of thieves and criminals who are multiplying the means to try to empty bank accounts. To avoid becoming a victim of this as much as possible, you have a major solution: It is highly recommended that you change your credit card code. This is the famous four-digit PIN between 0000 and 9999. This is the main security measure for credit cards.

Thus, specialists recommend not to bet on specific dates associated with special occasions (date of birth, for example) when determining your PIN code. In fact, nowadays, online, it is very easy to access your personal data. As a precaution, experts also recommend changing this code every three or four months. Needless to say, it is always better to memorize it and not write it in your wallet next to your card.
