Gerät für Fingerabdruck-Scanner in Android?

Question

iam läuft ein Projekt, dass ein Teil davon erfordert einen Fingerabdruck zu lesen. Die Plattform, die wir verwenden, ist ein Android-Handy (2.2).

Gibt es einen Fingerabdruckleser availble für diese Plattform? (Micro-USB, Stromversorgung Probleme, Treiber etc.)

Answer 1

There's a company called InnovateScan which sells a device called BlueFin. It connects by Bluetooth rather than USB. It's not cheap and it's not light. But Google doesn't seem to throw up anything else. Check it out.

Answer 2

Most android phones do not support USB host mode or have the drivers for usb devices without 'unofficial' kernel modifications. Nor can they supply power to a USB device.

But if you are up for a lot of hard work, kernel patching and reflashing, and set up ADB over wifi or something else since you will loose the existing USB (device) capability, you could probably get this working as a demonstration project.

As a product, you'd at a minimum need a vendor willing to sell you reflashable phones, and more likely you would want to replace the phone case with a larger one including the reader and necessary circuitry to tap power for it out somehow.
