Tokenization is a powerful technique used to enhance the security of sensitive data, such as credit card information. With tokenization, the Shift4 SkyTab POS system replaces the actual sensitive data with a unique identifier called a token. The token is meaningless to anyone who does not have access to the system’s tokenization database, which securely maps the token to the original data.

Tokenization process

When a transaction is processed using the Shift4 SkyTab POS system, the sensitive information, such as the credit card number, is encrypted and replaced with a token. This token is then sent for authorization and stored within the system. The actual credit card data is securely stored in the system’s tokenization database. When the time comes for a refund or chargeback, the token is used to retrieve the necessary cardholder information from the tokenization database. This ensures that sensitive card data is never exposed during transaction processing or storage.

Benefits of tokenization

Tokenization offers numerous benefits when it comes to data security. Firstly, it greatly reduces the risk of data breaches, as tokens have no value to potential attackers. Even if malicious individuals gain unauthorized access to the system, they will only encounter meaningless tokens instead of actual sensitive information. Additionally, tokenization eliminates the need for merchants to store sensitive card data, reducing their PCI DSS compliance scope and simplifying the security requirements for their systems.
