On Ubuntu 20.04, the only package avaible to install is libfprint-2-2 and libfprint-2-dev. Are those supposed to be compatible? Because I would assume not since npm i node-fprint fails.

First of all I've like to congrats you for this node wrap.

I'm working on a platform with a principal machine (server) and have some raspberries(clients) conected with my fingerprint lectors (Digital Persona U.are.U) where I'm expecting to have at least 500 different users. With the enrollStart() I'm saving the fingerprint String on a database, and when I need to Identify someone I create an Array as you have on the example. I see that the identifyStart() needs this array and when you put the finger in compares, but Is there a way with this library where I can read only the fingerprint on my client, and send it to the server and compare it there?

Thanks for your help and happy holidays!

I have tried to use this library on windows 10 but when i run the installation command i end up at getting following error:-

Call to 'pkg-config --libs libfprint' returned exit status -1073741701 while in binding.gyp. while trying to load binding.gyp

excute this command,
npm install node-fprint

below are the error log

Hi all
I'm using a digital persona device but many times identify service return identify-retry-scan results automatically we do not understand why it is happening.
please help me.

Hi Ephraim,

First of all, thank you for porting the fprint library to nodejs and node-red!

As part of my never ending quest to automate my home I am trying to set up a Digital Persona u.are.u 4500 fingerprint reader on a Raspberry Pi 2 running Raspbian Jessie. However I've run into a problem and I don't know how to solve it. Whenever I try to the code and try to enroll/verify a fingerprint I receive the following error:

pi@raspberrypi:~/node_modules/node-fprint/test $ node verify.js Found: Digital Persona U.are.U 4000/4000B/4500 enroll your finger! You will need swipe your finger 1 times. stage 1/1 uru4000:info [init_run_state] Versions 0010 and 0115

----presents finger on reader----

FATAL ERROR: v8::HandleScope::CreateHandle() Cannot create a handle without a HandleScope Aborted

Do you have any idea what is causing this exception and/or how to solve it?

Kind regards,

Marcel

node-fprint: 0.0.6
node-red-contrib-fprint: 0.0.4
Nodejs: 4.4.3-1
Raspbian Jessie Lite, March 2016
Kernel version: 4.4

i'm using nodejs 8.11.3 and when i try to run fprint.identifyStart i get a segmentation fault error and it stops working

is this possible add these functions on next release ?

• getImgWidth
• getImgHeight
• imgCapture

fp_dev_img_capture (struct fp_dev *dev, int unconditional, struct fp_img **image)
fp_dev_get_img_width (struct fp_dev *dev)
fp_dev_get_img_height (struct fp_dev *dev)

Hello,

So much appreciation for your giving the world this library! We used it in a major project some two years ago, and it was awesome; it helped greatly. Thank you!

1. The Challenge
We currently have a good number of stored fingerprints captured/enrolled with this library, encoded with the toString function. The decoding function fromString would be needed to return them to raw bytes, for identification/verification.

2. Assistance/Help Request
Since this library won't work with the latest version of libfprint (currently at v2), can you please give a lead/clue as to how the fromString(...) function can be implemented in either python/JavaScript? A pseudo-code could go a long way, please.

3. Why needed
Having the fromString(...) function in any of those two languages will allow us revert the stored fingerprint data to raw bytes, and then use them in our identification/verification routines implemented with libfprint-2-2 (with python/javascript binding). Our team isn't too good with C++.

Thanks and regards, please.

Foluso.

Before i get too deep here, I am trying to understand if this can be packaged into an electron app and be used across platforms. Is this possible?

Could you please create an example on how to use this API? I have no clue at all.

Thanks,

When I spend 54 or more fingerprints for identifyStart function, it does not turn on my reader, maybe an overflow of fingerprints? kk

Hi,

I get the following error when I try to run the install command (npm install node-red-contrib-fprint). What I did wrong? Please advice, thank you. Regards, Les:

pi@raspberrypi:~/.node-red $ npm install node-red-contrib-fprint
