The funny thing is to see Samsung and Google going again for different solutions, messing things up in an already fragments operative system
Not true. Google Wallet and ApplePay are not available in many countries... like South Korea (Samsung's native market), or Australia (Which has 10x more NFC terminals than the US and 4x more than the UK.)
Samsung is putting payment solutions into their devices to allow their consumers in those countries to access mobile payments as well.
Neither Google nor Apple have announced a timeline to expand into other countries.
