First of all “Apple Pay , then “Samsung Pay and now its time for “Android Pay”. Sundar Pichai (Google SVP) at MWC (Mobile World Congress) in Barcelona , Conformed that Android Pay is coming. Android pay will be creating a platform for developer to build payments into their apps, Dont get it wrong there will be no separate app like Wallet. OS-level service that makes it easy for app makers or retailers to let you buy things using your Android device.
While Apple Pay allows user to buy stuff in physical store by NFC , Android pay will allow retailers to offer online checkout options using its platform.
Sundar Pichai didn’t go to deep about this topic,but did confirm that it will offer similar features to its rival.
