For Fujitsu, fingerprint readers on smartphones are old hat; on Android tablets, however, they're still rare. The company should make those sensors easier to find with its latest Arrows Tab, the FJT21. The 10.1-inch slate uses its fingerprint reader to streamline Android 4.2's multi-user support, signing anyone in with a swipe. Families can also implement both a simple mode for newcomers and a content-restricted kids' mode. Fujitsu isn't leaning solely on sign-in technology to sell its tablet, though. The FJT21 centers on a 2,560 x 1,600 LCD with Gorilla Glass 3 protection; under the hood, there's a fast 2.2GHz Snapdragon 800 processor, an 8-megapixel rear camera, a 1.3-megapixel front camera and 64GB of expandable storage. Japan's KDDI will ship an LTE-equipped version of the new Arrows Tab in late November. Sadly, it's doubtful that we'll see an equivalent model reach the US.
