On the Robokassa page, to enter bank card data, you will need to enter bank card data: card number, cardholder name, card expiration date, three-digit security code (cvv2 for visa, cvc2 for Mastercard, additional identification code for МИР). All necessary data is printed on the card itself. The three-digit security code is the three numbers found on the back of the card.
Next, you will be redirected to your bank’s page to enter the security code that will be sent to you via SMS. If you have not received the security code, you should contact the bank that issued your card.
