At its I/O conference, Google's just revealed that it will standardize fingerprint ID security across Android M devices, so that manufacturers like Samsung don't need to build their own. That means developers will be able to use an open system that lets you unlock your device, buy with Google Pay, pay at Google's Play store and perform other common functions with your digits. The system will also be bundled in its API to help developers integrate it into third-party apps. In other words, it'll work much like Apple's fingerprint system already does.
