There are several models of smartphones with fingerprint scanners available, but the technology is provided by external companies, so they differ from each other. Google would like to change and implement such sensors directly in the operating system. So maybe it will be equipped with upcoming Android M.
In the case of iPhone, biometric technology is provided by Apple and this ensures full compatibility between hardware and software. For Android, the issue is different, because although there are several models of smartphones with this solution, the technology is provided by different companies and each system is different.
Google would like to change this by creating one standard, so as reported sources, the company wants to equip its latest Android M platform to support this technology. Sources say the Mountain View company already wants to implement it for Android 5.0 Lollipop, but it's unclear why she changed her mind. It is also said that this solution will be available to application developers so that they can use it in their own solutions, such as user authorization.
