Processing card payments is a great responsibility for businesses, especially when it comes to the transmission and storage of confidential information. Even with the modern security measures, in the first half of 2021 alone, there were 1,767 publicly reported breaches that exposed 18.8 billion records.
But how not to become one of the victims of fraudulent activity and protect the clients’ payment data effectively? This practical guide has all the expert advice on storing credit card information that a merchant needs.
No matter on what scale your company operates, it is essential that it complies with the Payment Card Industry Data Security Standard. According to it, every merchant dealing with credit and debit card processing must take measures to safeguard the consumers’ vulnerable information and prevent system breaches.

Now that you are aware of the types of cardholder details allowed for storage let’s take a look at the undesirable ways of collecting credit card information online.
Here are some examples of practices that undermine data storage security:
1. No PAN Encryption

2. Giving Employees Excessive Access
Approximately 75% of breaches happen due to privilege misuse. This typically occurs when employees receive more data access than their job functions require. Nevertheless, statistically, less than half of businesses have a password vault, and only 21% of companies implement multi-factor authentication for privileged access.
3. Paper Format
As outdated as it might seem, some merchants still list clients’ payment information on paper. No matter if the records are kept in organized files, it is one of the riskiest methods of storing credit card numbers vulnerable to both internal and external fraudulent activities.

Such organizations will place vulnerable information on secure servers. This alleviates the burden of PCI compliance to a certain degree by taking care of the most challenging aspects of the regulations.
Knowing and applying what the storing credit card information law requires is already a huge step towards securing the card payment details. However, there are some more important factors to keep in mind:
Besides, remember to stay updated on the upcoming PCI DSS v4.0 and stay compliant with the new regulations. Following all the advice mentioned above will keep your clients’ card information at minimal risk of breach.
