Multiple Smart Cards

Hi everyone!

How does Adobe Acrobat chooses a smart card to decrypt an encrypted pdf when there are multiple smart cards available?

Example:

There are two smart cards available, each has its own certificate. Let's call them card1 and card2. (Both of them are currently inserted)

Procedure:

1. Encrypt pdf file with certificate available in card1.

2. Open the encrypted pdf. (chooses a smart card and then it will search for the certificate then perform decryption)

Adobe Acrobat automatically chooses a smart card to use; it could be card1 or card2.
