# PIN operations using PKI

> Endpoint for Card PIN operations using public key cryptography.

**Note:** If this endpoint is used, the client must make sure that the RSA key pair is generated and used by the card-holder device, giving no access to the private RSA key to any other system. This way, no other system will have any means to access the PIN code.
