Dell announced today that its XPS 13 and XPS 15 laptops now can be configured with a fingerprint sensor built into the keyboard for an extra $25. The sensor is compatible with Windows Hello, Microsoft’s system for alternative, faster login methods on Windows 10, making it a useful addition to the devices. And the price is on par with external solutions, so it’s a good deal if you’re looking for the feature.

The option is available on all versions of the XPS 13 and XPS 15, including the entry level spec models, which is nice. Both the XPS 13 and XPS 15 are available for purchase with the new sensor today from Dell’s website.
