What is the specific feature of a transfer via the internet?

You can use the card-to-card transfer service on the internet only for cards that support 3D Secure technology. Transfers are available for cards issued by Russian banks of the Visa and Mastercard payment systems. If a transfer was mistakenly sent to the actual card number of another recipient and you received a notification confirming the transfer was successful, it is impossible to make any changes to the transfer or revoke it.
