Client-Side Encryption (CSE)

In ecommerce and mobile apps, this is a programming technique used to encrypt sensitive cardholder data on the client side and securely transfer this data to the payment gateway to process a payment.

Adyen has implemented its own highly reliable and robust JavaScript library to perform client-side encryption, and merchants can integrate this library into their existing website or mobile app using a personal URL provided by Adyen. For more information, refer to Client-Side Encryption.
