Fingerprint recognition

From iPhone 5s to iPhone 6 / iPhone 6 plus, Apple has raised the status of fingerprint recognition technology from "optional" to "standard". Samsung is also doing the same thing, using fingerprints as a solution to smart device security issues. Fingerprint recognition security systems have begun to spread into a variety of fields in recent years, and technology companies are expecting a major expansion into electronic devices, storage units, and access control systems in 2015.
