The service is not free. Don't expect free services because: - Opening a card will require payment (about 3,000 rubles, the exact amount will depend on the exchange rate) - Maintenance will also cost money (around 3,000 rubles per year) - You will also have to pay for transactions. Overall, the fees here are slightly more favorable than in other services. For example, the money paid for opening the card counts towards the first year of maintenance. Additionally, there is no fee for depositing funds, and the amounts are a bit lower. In terms of convenience and reliability, everything is fine. This is an ordinary virtual card for online payments (if imported into a payment app on your phone, it can be used at checkout). Payments go through without delays, and the money is deducted instantly.
