Hi,
You need to convert the image to a byte array and store that. Typical way to do that is to save it to a stream.

Most of the finger print readers grab the images of your finger impressions in gray scale format. So a pixel represent a value between 0-255. But this for display purpose only.

You told that you are going to use the SDK:
* DermalogZF1 SDK
And the scanner
* Dermalog ZF1 Scanner connected

If you explore the samples from their SDK, they use image for display purpose only. They may need a data structure like Finger print Registration template, verification template.

So you should store the registration template in the database not the raw pixel (If you know how to do image matching on finger print then you may :)

Then when user verify their finger print, you should compare the one (using their sdk) coming at present with the db persisted info to know who is that blackship :) putting his finger in the finger reader (Or Scanner)
