Is it valid to send and getApplicationId after selecting an application other than aid=0x00 00 00.

or is it mandatory to send SelectApplication with AID=0x00 00 00 before sending getApplicationId apdu?

Hi Eshwar chandra Pavaganda,

it only works on the PICC level, so on AID 0x000000

when you have a different application selected, you will get an error code

what also works is to only activate the card on ISO Layer 3+4 and then directly send the cmd.GetApplicationIDs, without a Cmd.SelectApplication (0x000000).
