Login to Windows just by walking up to your laptop. Dell's ExpressSign-in security feature works with Intel's Context Sensing Technology to automatically wake or lock the laptop before the IR camera even has a chance to work.

Unveiled at CES 2019, the Latitude 7400 2-in-1 had its own little corner on the Dell show floor to showcase its ExpressSign-in feature. With the help of an integrated proximity sensor, users can simply walk within 5 feet in front of the laptop to automatically sign in or sign out without needing to look at the camera, type a password, or touch a fingerprint reader. Dell is now ready to ship the Latitude 7400 2-in-1 for $1600 and up.

Based on our experience with show floor models, the ExpressSign-in feature can be finicky if you're not approaching the laptop straight on or if strangers are standing nearby. Indeed, Dell suggested passersby to step aside and keep their distance during the CES demonstration. We always recommend enabling multiple sign-in measures for added security instead of relying on just one single technology or method. Thus, Dell's ExpressSign-in feature should be seen as another layer of security on top of the usual IR webcam and fingerprint reader.

Core specifications are otherwise typical for an ultrathin business laptop including the ULV Whiskey Lake-U CPU with vPro, 14-inch FHD touchscreen, and M.2 storage. Of particular note is its dual Thunderbolt 3 ports for a wide selection of docking options.

Expect our review on the Dell Latitude 7400 2-in-1 in the coming weeks. The Latitude 7400 2-in-1 differs significantly from the new Latitude 7400 which is both larger and heavier and omits the ExpressSign-in functionality.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
