Via online banking
Some online banking services have templates for adding money to Yandex.Money Wallets. You need to find Yandex.Money in the list of payments, specify your Wallet number and amount and to confirm the transfer.
Sberbank Online, Pochta Bank, Promsvyazbank, Uralsib, Alfa-Click, and many other banks provide these transfers without commission.
Maximum deposit amount is 15,000 rubles if your online banking does not set its own limits.
If your bank is not in the list, make a transfer to the banking details: you can copy them to your online banking.
You can also transfer money from your bank card to the Yandex.Money card: it shares the overall balance with the wallet. Simply make a card to card transfer, as usual.
