Fingerprint authentication is nothing new. Enterprise s have had it for years. Apple introduced Touch ID in the ione 5S in 2013. Sporadic Android phones have unlocked with your touch over the years as well, like the Motorola Atrix recent Samsung Galaxy phones. But Android-based implementation of fingerprint recognition has never been centralized around a stard A—until Android M.

The new fingerprint A in Android M brings many of the conveniences of Touch ID to ’s platform. On Android M phones equipped with a fingerprint scanner, you’ll be able to unlock your device with a touch, as well as use your finger to authenticate purchases made in the ay Store or with the similarly new Android y (which itself mimes Apple’s Apple y service, which was introduced last year).

The fingerprint A is also being made available to developers to integrate inside their own Android apps. A Target app that used the fingerprint sensor to authenticate your Target account was shown on stage.

l in all, Android M’s new fingerprint support isn’t anything revolutionary, but it’s nice to see ’s mobile platform staying competitive with the ione on the feature front. It’ll be exciting to see how developers take the fingerprint A run with it once Android M rolls out in the third quarter of the year.
