Although an alphanumeric password is highly regarded as an effective way to prevent an unauthorized person from accessing the information on a smartphone, fingerprint technology has added an extra layer to smartphone security. Specifically, a fingerprint sensor prevents anyone without a stored fingerprint from logging into the phone’s operating system. In addition, many cellphones with fingerprint sensors also allow their users to make payments, authorize transactions and verify their identity. Consider buying a cellphone with a fingerprint sensor if you store a lot of personal information on your mobile device.

The Apple iPhone 6 Plus is an excellent example of a modern smartphone that has an integrated fingerprint sensor. This smartphone is one of Apple’s flagship mobile devices. It has a 5.5-inch screen that delivers great HD visuals, an 8-megapixel iSight camera for taking clear pictures and an A8 chip with 64-bit architecture that provides outstanding performance. The fingerprint sensor is called Touch ID and it reads any fingerprint that touches the Home button. You can activate the security feature by configuring the device’s Touch ID and Passcode settings.

If you prefer the Android mobile platform, the LG Nexus 5X has all the features that you would expect from a top of the line Android phone with a fingerprint sensor. The Nexus 5X has a snapdragon 808 processor, a 5.2-inch display and runs on Android 6.0 Marshmallow. Conveniently located on the back of the device, the 5X’s fingerprint sensor can help you unlock your apps, turn on your screen and pay for products through Android pay with one just touch. In addition, the phone’s Imprint technology improves the sensor’s accuracy with every touch.

Another cellphone with a fingerprint sensor is the Ulefone Be Touch 2. This smartphone runs on Android 5.1, has a 5.5-inch display and 3GB of RAM. Similar to other fingerprint-enabled smartphones, the Ulefone’s fingerprint sensor is located in the device’s Home button. The scanner features 360-degree rotation, which helps to accurately identify your fingerprint.

Along with other security measures, such as using a virtual private network, cellphones with fingerprint sensors can provide much-needed protection against hackers.
