Western democracies are indeed looking to extend the current card based platform for as long as they can. That said, mobile payments is the future particularly among the youth under 30, of the western democracies. As for the rest of world, which is larger than the North America, Europe & Australia, card based systems are not in the... wait for it... "cards" 
(I know a bit lame) b/c there is no point in going backwards to install the old infrastructure that we are busy milking. Card payments rode to prominence on land lines and a government back postal system with carriers, zip codes, etc. For most of the planet, where ever you go, there you are! You will be known/located by your cell phone. No need to stamp out plastic cards to be mailed to non existent addresses, to run on non existent or very thin land lines.
Clearly, we will need a dual system for some time to come. That said, BTC solutions should be low cost, secure and readily accessible.
