Is It Safe to Email Credit Card Info? Best Practices for Security

In today’s digital age, sharing sensitive information like credit card details often becomes necessary for various online transactions and purchases. However, the convenience of email communication raises concerns about the safety and security of transmitting such confidential data. In this article, we’ll explore the risks associated with emailing credit card information and discuss best practices to ensure secure transmission when it cannot be avoided.

Is It Safe to Email Credit Card Information?

The short answer is no, emailing credit card information is generally not considered a safe practice. Email, by its nature, is an insecure communication method that lacks built-in encryption and protection measures. When you send an email containing sensitive data like credit card numbers, it traverses through multiple servers before reaching the intended recipient, making it vulnerable to interception and unauthorized access at various points along the way.

Furthermore, once the email reaches the recipient’s inbox, you have no control over how they handle or store the information. The email could be forwarded to unintended parties, accessed by hackers who compromise the recipient’s email account, or even inadvertently exposed if the recipient’s device is lost or stolen. Given these inherent risks, it is advisable to avoid emailing credit card information whenever possible and seek more secure alternatives.

Risks of Emailing Credit Card Details

Emailing credit card information exposes you to several significant risks, including:

  • Identity theft: If your credit card details fall into the wrong hands, criminals can use the information to make unauthorized purchases, open new accounts in your name, or even steal your identity.
  • Data breaches: Email servers and service providers are frequent targets of cyberattacks. In the event of a data breach, your sensitive information could be compromised and sold on the dark web.
  • Compromised email accounts: Hackers can gain access to email accounts through phishing scams, weak passwords, or malware. Once an account is compromised, any sensitive information shared via email becomes accessible to the attackers.

Lack of Control Over Shared Information

When you send an email containing credit card information, you relinquish control over how that information is handled and who has access to it. The recipient may unintentionally or deliberately share the email with others, forward it to unsecured email addresses, or store it in an unprotected manner. This lack of control significantly increases the risk of your sensitive data falling into unauthorized hands.

Moreover, if the recipient’s email account is hacked or their device is compromised, your credit card information becomes accessible to the attackers. Once the information is out of your hands, it becomes incredibly challenging to ensure its security and prevent misuse.

Best Practices for Securely Sending Credit Card Info via Email

While it is strongly recommended to avoid emailing credit card information altogether, there may be situations where it becomes unavoidable. In such cases, follow these best practices to minimize the risks and ensure a more secure transmission:

Using Separate Encrypted Documents

Instead of including credit card details directly in the email body, store the information in a separate text document or PDF file and attach it securely. To protect the file, use strong encryption methods such as AES (Advanced Encryption Standard) encryption, which can be applied using programs like Microsoft Word or 7-Zip.

When creating the encrypted file, choose a strong and unique password that includes a combination of uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable information like birthdays or names.

Sharing Passwords Securely

Once you have encrypted the file containing the credit card information, it is crucial to share the password with the intended recipient securely. Avoid sending the password in the same email as the encrypted file, as this defeats the purpose of encryption. Instead, communicate the password through a separate channel, such as a phone call or a secure messaging app.

When sharing the password verbally, ensure that you are in a private setting where others cannot overhear the conversation. If using a messaging app, opt for one that offers end-to-end encryption, such as Signal or WhatsApp, to minimize the risk of interception.

Sending From a Secured Network

When sending an email containing sensitive information, it is essential to do so from a secured and trusted network. Avoid using public Wi-Fi networks or shared computers, as these are more susceptible to security breaches and malicious activities. Instead, send the email from a private, password-protected Wi-Fi network that you trust.

Additionally, ensure that your device is protected with up-to-date antivirus software and firewalls to minimize the risk of malware infections or unauthorized access.

Deleting Emails After Sending

Once you have sent the email containing the credit card information, it is a good practice to delete it from your sent folder. This reduces the risk of unauthorized access if your email account is compromised in the future. Similarly, instruct the recipient to delete the email after they have securely retrieved the necessary information.

Keep in mind that deleting an email does not guarantee complete erasure, as copies may still exist on email servers or backup systems. However, it does minimize the chances of the information being readily accessible to potential attackers.

Alternative Methods for Sharing Credit Card Info

Given the risks associated with emailing credit card information, it is advisable to explore more secure alternatives whenever possible. Here are some options to consider:

Using Secure Digital Vaults

Trustworthy digital vaults, such as Trustworthy, provide a secure platform to store and share sensitive information, including credit card details. These vaults employ bank-level encryption, two-factor authentication, and strict access controls to ensure that your data remains protected.

With a digital vault, you can grant specific individuals access to your credit card information while maintaining control over who can view and use it. This eliminates the need to send the information via email and provides a more secure and manageable solution.

Encrypted Messaging Apps

Encrypted messaging apps, such as Signal, WhatsApp, or Telegram, offer end-to-end encryption, which ensures that only the intended recipient can read the messages. These apps provide a more secure alternative to traditional email communication for sharing sensitive information like credit card details.

Some messaging apps also offer additional security features, such as self-destruct messages that automatically delete after a specified time, further reducing the risk of unauthorized access.

Providing Details by Phone or Fax

If possible, consider providing credit card information over the phone or via fax instead of email. While not foolproof, these methods are generally considered more secure than unencrypted email communication.

When sharing details over the phone, ensure that you are speaking to the intended recipient and that the call is taking place in a private setting. For fax transmission, confirm with the recipient that they have a secure and dedicated fax machine that is not accessible to unauthorized individuals.

Submitting Through Secure Websites

Many websites that require credit card information for transactions or payments use secure, encrypted forms for data submission. Look for websites that use HTTPS (Hypertext Transfer Protocol Secure) in their URL, as indicated by a lock icon in the browser’s address bar. HTTPS ensures that the data transmitted between your browser and the website is encrypted and protected from interception.

Before entering your credit card details on a website, ensure that your device is free from malware and that your antivirus software is up to date. Additionally, avoid clicking on suspicious links or downloading attachments from unknown sources, as these could be attempts to compromise your security.

Monitoring Credit Card Activity

Regardless of the method you choose to share your credit card information, it is crucial to regularly monitor your credit card activity for any suspicious or unauthorized charges. Most credit card issuers provide online portals or mobile apps where you can easily review your transactions and set up alerts for unusual activity.

If you detect any fraudulent charges, report them to your credit card issuer immediately. They will typically investigate the matter, reverse the charges, and issue you a new credit card if necessary. By staying vigilant and promptly addressing any suspicious activity, you can minimize the potential damage caused by credit card fraud.

In conclusion, while emailing credit card information is not recommended due to the inherent security risks, there may be situations where it becomes necessary. By following best practices such as using encrypted files, sharing passwords securely, and sending from a trusted network, you can reduce the risks associated with email transmission. However, whenever possible, opt for more secure alternatives like digital vaults, encrypted messaging apps, or secure website forms to safeguard your sensitive financial information.
