I. Stripe's Overall Security Architecture

1.1 Data encryption and transmission protection

Stripe has passed the highest level of PCI DSS Level 1 certification, which is the global security standard for the payment card industry and is achieved by only a handful of payment providers. This means that when using Stripe to make payments, merchants are not responsible for their own PCI Compliance pressure.

1.3 Zero-touch card information: Tokenization techniques

To further reduce the risk of compromise, Stripe employs a "tokenization" mechanism:

• The customer payment information is converted into a temporary token

• This mechanism effectively avoids the risk of leakage of customer card numbers due to hacking of the website
