Token usage is where the token is used for transactions, replacing the sensitive payment card data. This is the ultimate goal of tokenization!

By using the token, merchants and payment processors can:

1. Process transactions without storing or transmitting sensitive payment card data.

2. Reduce the risk of data breaches and compliance risks.

3. Improve security and privacy for payment card data.

The token is used in place of the payment card data, allowing for:

1. Secure payment processing

2. Fraud detection and prevention

3. Compliance with regulations (e.g., PCI-DSS)

Token usage eliminates the need to store or transmit sensitive payment card data, reducing the attack surface and making it much harder for attackers to access sensitive data.

And that's the entire process! From PAN input to token usage, tokenization ensures the secure and private use of payment card data.
