PSAM card

1. Product introduction

The products comply with ISO 7816 specification, China financial IC card pilot PSAM card application specification, social security PSAM Application guide and Sinopec refueling integrated circuit (IC) card application specification. The product can safely store keys and use these keys to calculate ciphertext for other applications or smart cards. It can realize interactive authentication and ensure the authenticity of terminals and customer cards. The security message mechanism realizes the security of data transmission between the card and the terminal / server, prevents the data from being monitored, replayed or changed without authorization, and the key dispersion function ensures the security of the master key.
