VISA and Mastercard in Russia

[gadje]

I didn't follow the news closely but I saw headlines on TV that VISA and MasterCard no longer work in Russia. What I saw was that cards issued abroad do not work in Russia, and cards issues in Russia do not work abroad.

Does anyone know if Russians have their own card networks? I mean does the average Vladimir have issues when taking money from ATM and using their cards to buy groceries? Are there other networkes that allow ATM and Debit cards to work?

What about American Express, Discover, do they have a presence in Russia?

Thanks
