Integrating customers smartcard infrastructure

[bwofsi]

Hello,

We'd like to integrate with some customers smartcard infrastructure.
We cannot control which cards and standards are used and therefore would need an MCU that can read all cards possibly in use.
Private keys will be provided by the customers.
If we'd need several MCUs, please tell us the complete list.

Best wishes,
Fabiano

Sorry for being unprecise. I meant contactless smartcards.
