Dell has added a fingerprint reader option to both the new Dell XPS 13 and XPS 15, giving buyers even more reason to purchase some of the best laptops currently on the market.

The fingerprint reader option was first revealed when Dell announced the upgraded XPS 15 (9560), although it wasn't clear how much the optional extra would cost. As it turns out, it's pretty cheap to add the sensor to the XPS 15; it'll set you back just $25 when added to any configuration.

You can also add a fingerprint reader to the new Dell XPS 13 (9360), a laptop that first hit the market a couple of months ago. Like with the XPS 15 option, adding a fingerprint reader to the XPS 13 only costs $25.

The fingerprint reader on both laptops is fully compatible with Windows Hello, which makes it fast and easy to secure your device. It's located below the arrow keys in a reasonably convenient position for everyday use.

The Dell XPS 13 and XPS 15 are already very configurable laptops. The XPS 15 comes with a high-performance Intel Kaby Lake CPU and Nvidia GeForce GTX 1050 graphics, along with an optional 4K display and loads of storage and memory configurations. The XPS 13 packs a U-series Kaby Lake processor, an optional 3200 x 1800 display, and a number of PCIe SSD options.
