Fingerprint scanning is nothing new to computing devices, like other forms of biometric recognition. While scanners have been on laptops for several decades now, the Pantech GI100 in 2004 was the first mobile phone to have one. During the smartphone era, though, they came back in a big way, because of the ever-growing need to protect the data in our pockets.

In 2013, with the launch of Touch ID, the Apple iPhone 5S became the first major mobile device in the U.S. market to have a fingerprint scanner. Although Apple has since phased out this feature with facial recognition, all smartphones have become standard with fingerprint scanners. Most of them put biometrics on the device 's back or side.
