The easiest and less elegant way is to use only SCardConnect in a loop
(with a delay like 200ms) until it returns OK. It may not look
beautiful but works anywhere.

Some may argue that in a shared environment with multiple smart card
software running this would not work because one of the programs could
lock the card. In this case SCardConnect will return
SCARD_E_SHARING_VIOLATION so you still know there is a card.
