Android Pay and Support for Fingerprint: Android Pay, Google’s answer to Apply Pay, will also be a part of Android M, although you will need an NFC enabled device to use the feature. Google says Android Pay is secure because it only uses a virtual card number during the transaction and not your real credit/debit card number. Android Pay will work at 700 partner-stores in the US including Macy’s, etc.
Google is also working with app developers to allow more of these to use Android Pay.
Android M will get FingerPrint Support as well. The API for Fingerprint will be available for developers as well and they can incorporate it into their app as well. Google says it will work “across a range of devices and sensors,” so it’s not clear how devices without fingerprint scanners will support this. – See more at: http://indianexpress.com/article/technology/tech-news-technology/android-m-at-google-io-2015-permissions-to-android-pay-all-the-new-features/#sthash.hAsp35QE.dpuf
