Biometric Template type

[Clément 143]

Hi,

I'm using our beloved Delphi to capture fingerprints from a device and send them to another device. Usually, small Biometric Desktop USB device is used to capture fingerprints, and I send the data to controller (Door, etc). 

I specifically asked the controller manufacturer to have his device compatible with ANSI378-2004, as the biometric Desktop USB supposably captured in that format.
The Controller manufacturer is saying that ANSI378-2004 template should begin with 46 4D, but of course none of the templates I capture begins with those bytes. And the desktop manufacturer says the format of his device is ANSI378-2004. 

 

Is there any library (or application) that can help me identify the biometric template format? I was ask to find something, but as it seems there's a strong copyright over those modules, there's no much information. 
Anyway, maybe someone can shed some light.

 

Thanks

google found this on the first place:

https://templates.machinezoo.com/ansi378-2004

 

first 26+ bytes are "ANSI INCITS 378-2004 template", don't ask me what is it, but this lead to this site:

and this dl link "INCITS 378 index finger minutiae templates - 233K. Last updated Oct 3 13:24"

 

where are .frmpiv files in it, which contain 

0000000050: 00 00 00 00 00 00 00 00 │ 46 4D 52 00 20 32 30 00          FMR  20
0000000060: 04 40 FF FF FF FF 80 01 │ 01 D0 02 20 00 C5 00 C5  @ÿÿÿÿ€Ð  Å Å

 

there is your header magic, 46 4D 52 = FMR

That was fast! I past so many times over those pages but I guess I needed an extra pair of eyes!

Thank you
