Fingerprint imaging app

Questions about Thunkable
1

Hi Guys,

I was wondering if there is an easy set of steps to create a simple app to capture images from a fingerprint reader (plugged into a phone with a usb to usb-c adapter).

This is an example of the kind of fingerprint reader which claims to be compatible with android:

I want it with a clean and simple, a black and white image of the fingerprint.

would probably just need a ‘re-take photo’ button on there to.

the only other feature would be the ability to share on WhatsApp so i can send it to myself.

Any help would be greatly appreciated.

the traffic is slow on thunkable forum these days. I remember the days where it was almost like instant chat.

Hey @FamousMrThomas :wave: (great to see you still in the Community!)

Not familiar with this specific piece of hardware, but in general, we don’t have serial port access for Android (or iOS if the device has USB-C) Typically you’d need an additional USB-OTG converter to enable this

If the scanner had BLE that might be easier to connect to - but transmitting larger images may be problematic.

Ideally, you’d need an IoT version of this scanner; push the images to (local or remote) cloud storage and then use the API blocks to fetch the data. You might end up spending a little more on the hardware but you’ll save hours on dev time.

Are you just experimenting with this fingerprint scanner or are you thinking about buying/distributing several of them?

Hi Domhnall,

Thanks so much for dropping me a line. Great to speak with you again. Thunkable is always my first thought when it comes to apps. I am lucky enough to be in the development stages of my idea, so any help now will save time later. I have taken your recommendations and am looking into them.

Thanks again, and if anyone else might have any innovative ideas as to how this might be made easy… I like easy! Lets make some of the more interesting ideas accessible to the world. sometimes it’s nice to make things for granted (calculator app).
