You can use any card together with your Wallet: salary card, debit card, credit card. Link it with your Wallet for fast payments or just pay with it and make transfers.
In support of your Wallet, you can issue a Yandex.Money MasterCard (physical or virtual). This will turn your Wallet into an online banking service for this card.
You can enable multicurrency support for any Yandex.Money card: rubles, dollars, euros, tenge + 7 more currencies. The card will switch between currencies automatically (you won't need to link it to different accounts).
