Page 6 describes the command packet, which must be 10 bytes. A word is two bytes, a dword four bytes. If your numbers aren't big enough to fill the upper bytes, you'll still have to send the extra bytes as zeroes (or two's-complement if the data is signed). You might try asking in our <a href="http://forum.sparkfun.com/" rel="nofollow">forums</a> as well. Good luck!</p>

Thank you so much for replying</p>

I connected the reader by usb and run the demo software .
I enrolled a few fingers and it worked surprisingly well , after a while of fiddling with the unit i closed the usb connection and unplugged the unit .
I thought of many places where i could put a fingerprint reader , i decided to install this one in my car .
Today i tried the demo software again , when i open the connection it displays serial and firmware versions , displays enroll count , deletes fingerprints , but does not enroll or read fingerprints any more .
When i click enroll the blue led flashes briefly in the reader and the software displays Device error! , if i click verify the blue led comes on but does not recognize a finger and after awhile displays time out ...
I may buy another but it would be nice to know why this one died ...
Maybe the writer of the demo software has not read the special note ?</p>

The ( unpopulated) J1 connector is the USB interface , and auto-installs as a CDROM device in windows. I just used an old USB AB cable , snipping off the 'B' end, and exposing wires ( red, white, green, black.)
They attach in that order starting from pin 1 (square pad).
The SDK_DEMO.exe software worked well (selecting 'USB') in win7 on my 64-bit machine, but not my 32bit XP desktop.

The J1 pads do not correspond to pins in the JST connection. The two pads farthest away from the "J1" silkscreen are both ground but the other three pads are not connected to any of the other JST pins.</p>

You could have the device scan the current user and then send you the template. You could then upload groups of 20 users and have the device compare to see if there is a match in that group. Repeat as needed.<p>I suspect this would be quite slow, though.</p><p>If you can figure out how to compare the templates yourself, you could just maintain the database of user templates elsewhere (e.g., in an Arduino) and do the matching yourself.</p></p>

I'm not sure if "J" stands for "jumper" or what but it's common to see connections with a J# silkscreen.
I found a connector that fit in my bag of old connectors harvested from old electronics.</p>

are these the same as the JST ? if so, one could make a break-out board, or put it on a prototype shield, the "ears" will help too, to have it mount steady.</p>

I am not entirely certain why Sparkfun included 2 different 4-wire JST connector cables in their "Selected by our staff" related items section, but it does cause some confusion. I forgot to originally order the cable with my fingerprint scanners and ended up having to order (separately) both kinds to ensure at least one would be the correct form factor. So, PRT-09916 (rainbow wires) is NOT the correct connection lead....PRT-10359 (black and white wires) IS the one you want for this application.</p>

(btw. your "greasy" vinger has to make contact with the "window" for the good working of it all)</p>

Press the tape to the scanner and remove. It does a fantastic job cleaning finger print sensors like this. If you are extra paranoid then dispose of the tape in a destructive manner because it does a great job lifting the print from the surface.<p>If you are worried about security then you should be worried that the response from the sensor for a 1:1 and 1:N verification is not encrypted and the verification takes place at the sensor. So, a would be hacker could just remove the sensor and send some basic serial commands to spoof the system.</p></p>

Essentially a properly warmed raw breakfast sausage link (if the scanner looks for body temperatures) placed over a scanner that already has a latent print on it will usually be recognized as the print.
