How It Works

Step 1: Scan or photograph your completed FD-258 fingerprint card. Use a flatbed scanner at 300+ DPI for best results, or a smartphone photo with good lighting.

Step 2: Upload your image to our converter. We automatically detect the card orientation and extract the three fingerprint regions.

Step 3: Verify the fingerprint regions look correct and enter your demographic information (name, DOB, etc. for the EFT header).

Step 4: Pay $10 via Bitcoin Lightning and download your EFT file instantly. Upload it to your ATF eForm and you're done.
