Card tokenization is the process of replacing sensitive payment card data, like credit card numbers, with a unique identifier called a token. This token can be used for transaction processing, while the actual card details are securely stored by a payment service provider (PSP) or a tokenization service provider (TSP).
Tokenization is a security measure that helps to protect customers from data breaches. If a hacker is able to breach a merchant’s website or database, they will only have access to the tokens, not the actual card numbers. This makes it much more difficult for them to steal customer data or commit fraud.
Tokenization also has a number of other benefits for both merchants and customers. For merchants, tokenization can help to reduce PCI compliance costs and improve the checkout experience for customers. For customers, tokenization can make it easier and faster to make online payments, and it can also help to protect them from fraud.
How Card Tokenization Works
Card tokenization typically works in the following way:
- The customer enters their card details on the merchant’s website or in their mobile app.
- The merchant sends the card details to the PSP or TSP.
- The PSP or TSP generates a unique token for the card.
- The PSP or TSP sends the token back to the merchant.
- The merchant stores the token in its database.
- When the customer makes a purchase, the merchant sends the token to the PSP or TSP.
- The PSP or TSP decrypts the token and uses the actual card details to process the transaction.
Benefits of Card Tokenization
Card tokenization has a number of benefits for both merchants and customers, including:
- Increased security: Tokenization helps to protect customer data from data breaches. Even if a hacker is able to breach a merchant’s website or database, they will only have access to the tokens, not the actual card numbers.
- Reduced PCI compliance costs: Tokenization can help merchants to reduce their PCI compliance costs. This is because merchants do not need to store or transmit actual card numbers when they use tokenization.
- Improved checkout experience: Tokenization can help to improve the checkout experience for customers. This is because customers do not need to enter their card details every time they make a purchase.
- Reduced fraud: Tokenization can help to reduce fraud by making it more difficult for hackers to steal customer data or commit fraud.
