Storing Payment Details Securely in the IXOPAY Vault
Protecting sensitive payment details like credit card numbers is crucial to online merchants. The IXOPAY vault provides a means of securing payment details like credit card numbers, international bank account numbers and alternative payment methods.
Secure Payment Details with Tokenization
Storing payment details is required for card on file transactions and subscription payments. Stored payment details streamline the checkout process for return customers, allowing them to simply choose a previously used payment method from a list. Customers can also set a payment method as their preferred method, and this method can automatically be pre-selected. Alternatively, the last used payment method can be selected by default. This removes the need to re-enter payment details and also eliminates the chance of entering incorrect payment details, causing the transaction to fail.
In order to comply with PCI DSS, credit card information must be stored in a secure PCI DSS certified vault. IXOPAY offers a PCI DSS Level 1 secure vault that both stores and tokenizes payment details. Tokenization is a security mechanism that replaces sensitive payment details - like credit card numbers - with a unique and random token that serves as a reference. As the token does not contain any underlying payment information, it can be stored by merchants without increasing their PCI DSS scope.
Merchants generally want to avoid handling any sensitive payment details directly, as doing so incurs significant overheads and require annual audits in order to meet PCI DSS requirements for cards. Outsourcing the storage to a third party results in significant savings, as the cost of PCI DSS certification can easily run into the hundreds of thousands of euros over time.
When submitting a transaction request using a payment instrument stored in the vault, the merchant simply includes the token in the transaction request. IXOPAY then uses this token to retrieve the actual payment details associated with the token and forward those when processing the transaction.
More Than Just Credit Cards
The IXOPAY vault is not only able to store credit card details in line with the PCI DSS requirements, but also IBANs and details on alternative payment methods like Google Pay and Apple Pay. To ensure that credit card details are neither stored nor handled directly by the merchant, special fields in their own iframe are used to enter the PAN and CVV on checkout pages. The data entered in these fields is forwarded directly to IXOPAY and is thus never visible to the merchant.
Whenever a customer completes a payment using a payment instrument that can be stored in the IXOPAY vault, you can offer them the option of saving that payment instrument for reuse. If this option is checked, the payment details are stored in the IXOPAY vault and a token is generated, which can be stored by the merchant to reference the payment instrument in future transactions.
Once payment details have been stored and linked to a customer’s account (using customer profiles in IXOPAY), you can allow customers to reuse the payment method at checkout without needing to re-enter their payment details. Consumers can set a payment instrument as their preferred option, which can be selected by default on the checkout page.
Having access to payment details is also required for recurring payments, e.g. for subscriptions. As these customers need to be billed in regular intervals (e.g. monthly), the payment details need to be stored in order to automatically process the subscription fees. This ensures regular and timely payment without needing to involve the customer in the process.
Card Updater: Ensuring Up-to-date Payment Details
One challenge that merchants face when storing payment details is the possibility that the details can change over time. This could be due to a card being reissued, for example. IXOPAY’s card updater allows you to automatically query credit cards stored in the IXOPAY vault for any changes to the underlying payment details and automatically update the stored information if there have been any changes.
A similar mechanism is also available in the form of network tokens issued by the credit card schemes. The schemes issue merchant-specific tokens for credit cards that are maintained by the schemes themselves. Even if the underlying credit card details are changed, the token continues to reference the card, meaning no updates are required on the merchant’s side. IXOPAY can request and manage these network tokens.
The Value of Independence
Merchants can also import existing payment instruments into the IXOPAY vault, allowing them to migrate from an existing system to IXOPAY’s payment orchestration platform. IXOPAY generates tokens for these imported payment instruments and provides merchants with information on which new tokens replace which old tokens. This allows merchants to update the tokens they have stored locally and ensures that customers are unaffected by the decision to migrate and do not need to update their payment details. Payment instruments that can be stored in the IXOPAY vault - credit cards, IBANs and alternative payment methods - can all be imported.
One of the major advantages of using IXOPAY for tokenization is that the IXOPAY tokens are not specific to a single payments provider. When PSPs issue merchants with a token, that token is only valid for transactions processed by that specific PSP. In contrast, tokens issued by the IXOPAY platform can be used with transactions that are forwarded to any of the hundreds of payment providers and acquirers supported by the platform. This is because converting the token to payment details happens before the transaction is sent to the payment provider or acquirer.
This can be particularly beneficial when using cascading and smart routing in a multi-acquirer setup, as transactions may be routed to different payment providers depending on the situation. If one PSP is currently unreachable, or if the merchant’s relationship with a PSP changes (contract is terminated by the PSP or the fees change, making the provider more or less attractive), the transaction can still be routed to an alternative provider using the token and stored payment credentials. IXOPAY thus helps avoid merchants from becoming highly dependent on a single provider (provider lock-in), giving them the freedom to pick and choose from the best payment providers for that merchant’s setup.
Advantages with IXOPAY Card Vaulting
IXOPAY’s secure vault delivers a number of benefits for merchants. It reduces their dependence on an individual PSP or acquirer by generating tokens that can be used with any provider connected to IXOPAY. This is a significant benefit for merchants using a multi-acquirer setup to help increase authorization rates, reduce costs and safeguard their business with fallback options. Storing payment details in a secure vault provides a high level of security and helps merchants meet their PCI DSS requirements while keeping down costs. IXOPAY’s card updater ensures that you keep credit card details up-to-date, which is vital to ensuring that recurring payments are processed successfully and customers are not required to update their card details if they are issued a new card.
Customers’ payment instruments can be shared across multiple merchants in IXOPAY’s tenant hierarchy using customer profiles. Payment instruments (credit cards, IBANs etc.) stored in the customer’s profile can be presented to the customer at checkout allowing them to choose which one to use and eliminating the need to enter their payment details again. Customer profiles also allow merchants to store the customer’s preferred payment method, as well as providing access to a customer’s full transaction history.
