Credit cards on file are a convenient way to make transactions online, but it's essential to understand how they work.
Many online services, such as subscription-based platforms, allow users to save their credit card information for future payments. This can be done through a process called "tokenization", where the credit card number is replaced with a unique token.
Having a credit card on file can make it easier to make recurring payments, such as monthly subscription fees. However, it's crucial to keep track of these transactions to avoid unexpected charges.
Some online services may also offer the option to save credit card information for future use, but this can come with security risks if not handled properly.

Benefits of Credit Cards on File
Credit cards on file offer many benefits, including faster checkout and improved cash flow. This is because customers can save their credit card information with a trusted merchant, making it easier to make purchases without having to re-enter their card details every time.
Faster checkout is a major advantage, as customers can complete transactions in a few clicks without having to enter their credit card information. This is especially convenient for customers who shop frequently or have recurring payments.
One of the key benefits of credit cards on file is improved cash flow. By setting up payment plans and having customers' cards on file, businesses can ensure that payments are made in a consistent and timely manner. This reduces the need for staff to chase customers down for payment, which can save time and reduce stress.
Here are some of the benefits of credit cards on file:
- Improve cash flow: Set-it and forget-it payments run on a schedule that guarantees payment will be collected when due.
- Reduce cart abandonment: Repeat customers don’t have to have their card in hand to make a purchase.
- Boost productivity: Streamlining acceptance frees staff to focus their time and efforts on important business areas.
- Increase security: Since card-on-file transactions are tokenized, stolen payment data is useless.
By implementing credit cards on file, businesses can also reduce the risk of manual entry errors and chargebacks. This is because the payment process is automated, eliminating the need for staff to manually enter payment information.
Security and Risk
Manual storage of customer credit card information is no longer acceptable by today's standards, especially when it comes to debit and credit card information.
A different take: Saving Account Information
Businesses must adhere to the Payment Card Industry Data Security Standard (PCI DSS) compliance regulations to protect customer card data and provide guidance on ways to improve and strengthen payment security.
Manual storage of customer name and credit card numbers on computer drives or master spreadsheets carries major risks, including the potential for hackers or malware to retrieve sensitive data.
Fraudsters can hack a customer's online account and place orders using the stored card, billing genuine shoppers for items they'll never receive, a risk known as third-party account takeover.
Merchants must implement security measures such as encryption, secure storage, and limited access to protect customer data and avoid legal penalties.
Keeping Customer Secure
Keeping customer secure is a top priority for any business. Manual storage of customer name and credit card numbers is no longer acceptable by today's standards, as it puts sensitive information at risk.
Payment solutions with automated card tokenization practices help prevent this risk by replacing actual credit card details with a random string of identification symbols, known as tokens. This form of encryption ensures that even in cases of a data breach, information remains safe.
Broaden your view: Credit Card Numbers and Information
Merchants must abide by policies set, laws made, and regulations in place, such as the Payment Card Industry Data Security Standard (PCI DSS), to ensure the highest level of protection when collecting, storing, and using credit card data.
Here are some key security measures to implement:
- Encryption: Converts plain text or card data into a coded message to protect its confidentiality and integrity.
- Secure storage: Use a secure server, firewalls, antivirus software, and other security measures to protect card data storage systems.
- Secure Socket Layer: A technology used to establish an encrypted and secure connection between a web server and a web browser.
- Limited access: Limit customer card file access to only those employees who need it to perform their duties.
- Routine updates & monitoring: Regularly update software and security measures to protect sensitive information and monitor these systems to detect and prevent unauthorized access.
- Retention Period: Establish a retention period for storing credit card information and regularly review and purge outdated or unnecessary data to minimize risk.
By implementing these secure payment storage practices, businesses can protect customer data, comply with regulations, and avoid financial losses.
Risk of Fraud
Fraudsters can hack into a customer's online account and place orders using the stored credit card, billing genuine shoppers for items they'll never receive.
This is called third-party account takeover, and it was responsible for causing the most financial losses to 13% of retailers in 2021.

Faulty Charges
Faulty charges can be a real headache for businesses.

You've billed the wrong amount, and now the customer is disputing the charge. This can happen when the wrong amount is charged to a customer's card on file.
A customer doesn't recognize the transaction and requests a chargeback. This can be a major issue if it happens frequently.
The customer's profile details—such as their credit card number or expiry date—are incorrect. This can prevent the business from charging the stored card and getting the required cash.
A customer's card may have expired, and the business may be unable to charge it. This may seem like a small problem, but it can quickly become a major issue if it happens to a large number of customers.

Policies
Having clear policies in place is essential for any business that handles payment information. A payment policy protects both your store and your customers in case of any issues with card on file transactions.
If a customer's bank shows an "insufficient funds" message, your payment policy can specify what happens next, such as resubmitting the payment attempt after two days. This removes the need for awkward conversations with customers.
To maintain compliance with payment industry rules and federal and state laws, you need a credit card on file policy. This policy helps you protect sensitive customer information and avoid potential fines and penalties.
Key requirements for a credit card on file policy include storing card details only when there's a clear business need, retaining only necessary information, and masking primary account numbers when displayed.
Some important compliance requirements to keep in mind are:
- Only storing card details when there is a clear business need to retain this information.
- Retaining only cardholder data, such as the account number and cardholder name.
- Masking the primary account number when it’s displayed.
- Using strong digital encryption techniques to protect credit and debit card information kept on file.
- Deleting card on file data once the business need to retain the information is no longer valid.
By following these guidelines, you can ensure that your business is compliant with payment industry rules and protects sensitive customer information.

Reauthorization
Reauthorization is a crucial step in ensuring that customers can make payments without any issues. You can run a reauthorization before giving goods to customers to check that their card is working.
If a customer has split their payments to pay half in-store and half in two weeks' time, reauthorize their card on file before billing the final amount. This is a great way to avoid any last-minute payment failures.

Reauthorization can be done using technology, making it a convenient and efficient process. For example, a business with CoF can perform a reauthorization to ensure a customer's card is working before a purchase is made.
To implement reauthorization, you'll need to have explicit permission to charge credit cards and store customer data securely. This is a must-have for any business that wants to accept card on file transactions.
Here are the key considerations for reauthorization:
- Payment policies
- Secure customer data
- Leverage technology
- Give notice of upcoming payments

Card on file transactions use credit or debit card information stored by a merchant, eliminating the need for customers to find their cards or key in details for a purchase. This convenience is especially beneficial for subscription purchases and recurring billing.
To initiate a card-on-file payment, customers can enroll their cards into their profile for future purchases, or businesses can use staff or automated software to initiate payments without the cardholder being present. However, customer permission is required for merchant-initiated transactions.
Card on file transactions require customer consent, which can be obtained in person, over the phone, in an online form, or through a merchant's app. During the enrollment process, customers enter the credentials for the payment method they wish to use and authorize the business to make future payments.
Businesses should clearly state the terms, including cancellation and refunds, timing, and frequency of future payments to avoid customer dissatisfaction or chargebacks. One best practice is to outline policies at the point of sale or on your website using common, easy-to-understand language.
