Mastercard accepts a digital currency that is authorized or developed by the central bank.
Mastercard will provide a money transfer system from the customer to the seller. The digital currency is government-sponsored.

With MasterCard joining now it is the first step of a bank company to recognize crypto currency as a currency and give a positive view of government in each country...

This is an insane news and will totally change bitcoins forever if it's truly implemented. I'm personally a big fan of the cards and master represents security so this will truly be a game changer any idea when it'll come out and which countries will it implement it in. We'll also have to consider fees that's also a important feature can they keep it low or not.

This will be good for them and helpful for joining earlier to compete with other and will also make them have more edge than visa.

My asshole puckers when I hear these words in one sentence, " fractional reserves of blockchain " We saw what happened with fiat currencies and the global economy, when they applied Fractional-reserve banking, so I hope they are not trying this with Bitcoin now. 

For those people who does not know what Fractional-reserve banking is, it is the practice whereby a bank accepts deposits, makes loans or investments, but is required to hold reserves equal to only a fraction of its deposit liabilities. Reserves are held as currency in the bank, or as balances in the bank's accounts at the central bank.

Essentially creating money out of thin air. 

Simply super! I'm glad that there is such news. And I very much hope that such similar and very promising projects will be more in the near future.

In this great prospects for this will come here all the big players.

I would honestly think that they finally recognize the true potential of Bitcoin and how blockchain could help them in the future. At first, they had some misunderstanding about Bitcoin, but now they do and hopefully others would follow suit. I also hope this is a good sign of things to come for Bitcoin. Cheers!

Yes it is better to have a card that will carry crypto or hold and could be used in a certain establishment where in crypto is accepted. In this way cryptocurrency would be put into good use and it will be functioning as real currency that could be use a medium of exhchange. This could be the start and i guess there are other company to follow seeing that there could  be a good income on joining cryptocurrency.
