Fingerprint scanning device in Android?

iam launches a project that requires part of the fingerprint. The platform we use is an Android phone (2.2).

Does this platform have a fingerprint reader? (micro USB, power problems, drivers, etc.)

There is a company called InnovateScan that sells a device called BlueFin. It connects via Bluetooth, not via USB. It is not cheap and it is not light. But Google doesn't seem to be throwing anything else. Check it out .

Note. I have no personal experience with this company or its products. No approval is implied or intended.

Most Android phones do not support USB host mode or have drivers for USB devices without “unofficial” kernel modifications. They also cannot supply power to the USB device.

But if you need a lot of hard work, patching and reflashing the kernel, as well as setting up ADB via Wi-Fi or something else, since you will lose your existing USB (device) ability, you can probably get this to work as a demonstration project.

As a product, you will at least need a seller who wants to sell you reusable phones, and most likely you will want to replace the phone case with a larger one, including a reader and the necessary circuit to turn off the power in some way.
