When your cardholders use their Adyen-issued cards for payments or ATM withdrawals, they may need to enter card data to authenticate the transaction.
You can use our API to implement functionalities that enable your cardholders to manage their card data. For example, you can:
- Reveal or change a personal identification number (PIN).
- Reveal card details, such as primary account number (PAN) or expiration date.
All these processes involve transferring sensitive card data between your servers and Adyen. To keep the data secure, all transferred data must be encrypted using methods such as the Advanced Encryption Standard (AES) and the ISO PIN block format 4.
While you can implement these algorithms by yourself, you can also use the encryption and decryption methods from our SDKs for iOS and Android.
The following pages explain how to manage card data using standard encryption methods or our SDKs. With our SDKs, you have the option to manage card data using secured sessions.
