How fingerprint scanner works in android device? Here below link is to show how a FBI certified fingerprint sensor works in the android device.

Let's take our SFT smart fingerprint android device model SF360 as an example, this one could do scanning, capturing, as well as do authentication on both device and fingerprint data server. Because the android device is using 4G or 3G or WIFI internet, thusit can send the fingerprint template in bmp,wsq etc to server and store. If the templates are stored the same with other fingerprint devices, you could also download the existing server template to the device and do matching in some places which may have no internet.
