Hey! Glad you finally here !
Wondering how you can ever add Biometric Fingerprint Authentication in a Node.JS Web Software application?
Worry NOT !
I will show you how I did it here below.
This web page here will not waste your time introducing Node.JS or attempt to discuss the Node.JS basics here. I understand you are here because you only want to know how to add Biometric Finbgerprint Authentication into your Web Browser based Node.JSsoftware application.
Why did your Company / Organisation choose to use Node.JS over the very many other Web Technologies available today?
I know you had Speed, Extensibility and Scalability in mind.
Considering the reliability of Node.JS to be the Best Open Source Bet for FullStack development and its Speed, Extensibility and Scalability, tell me why NodeJS is not one of the Best Engineered Web Technolgies in these modern times ?
Trully none comes close!
Node.JS ROCKS BIG TIME !
Now ……… here is an eye opener!
Biometric Fingerprint Authentication solutions need FAST SPEEDS! They need Super Speeds to work in industrial Web Browser based Software Applications like ERPs. This is where Node.JS stands tall among other Web Technologies.
Node.JS‘ Extensibility and Scalability makes it possible to integrate it with other additional functionalities as will be needed by an Organisation as their User and Client needs Grow! One of these Requirement that sooner than later becomes a necessity is the need to implement Access Control Features in an Organisation’s Node.JS software application to establish e.g Data Integrity, Enforce levels of accountability among users of system, Prevent Fraud among many other possible reasons.
Integrating your Node.JS software application with Biometric Fingerprint Authentication not only Helps you deploy a User authentication mechanism but Helps you know which particular User did what in the system because unlike Passwords, PINS or Secret Access Codes, Biometrics of a Person cannot be shared with another person. Biometrics traits of one person bear no resemblance with that of another person! Not even with Twins. This is what we call Non Repudiation

Accessories you need for NodeJS Biometric Authentication
In order for you to capture fingerprints for purposes of fingerprint enrollment and fingerprint authentication, you will need a couple of these items based on your integration needs.
Fingerprint Scanner / Reader . You will need a Fingerprint Scanner to capture fingerprint data into the phone.
Recommended Fingerprint Scanner / Reader(s)
Very many Fingerprint Scanner / Readers in the market DO NOT work with Web Browser based Applications developed in PHP, ASP.NET, Python, HTML5, Ruby on Rails and Node.JS.
Take note that you need specific type of reputable, tested and long lasting Fingerprint Reader / Scanners that work on Web for your Node.JS integration with Biometric Fingerprint Authentication project to be successful
As a result of this, you will find that there are few Fingerprint Scanners / Readers that you can rely on to use with your Node.JS software application to implement Biometric Fingerprint Authentication. The below is a list of Industry tested, reliable and trusted fingerprint devices that work seamlessly with Web Browser based Applications. They are;1. DigitalPersona 51002. DigitalPersona 51603. DigitalPersona 52004. DigitalPersona 53005. DigitalPersona 40006. DigitalPersona 4000B7. DigitalPersona 4500
If experimenting is not for you and you simply want a guarantee for what works in the market and you want to set your project milestones on a success trajectory path from the very onset, then these are the Fingerprint Reader / Scanners that will work well with your Node.JSSoftware Application’s integration with my Node.JS Biometric Fingerprint Authentication Software Pack.

Back-End Database, User Particulars and Biometric Data Enrollment
The Back-End Database used is MySQL.
Currently, I save the User Biometric Fingerprint Data and User Particulars in MySQL. I can Help you integrate with any other supported RDBMS that your Organisation uses like Oracle, MariaDB, PostgreSQL, MSSQL etc.
I used MySQL in this Node.JS Biometric Fingerprint Authenticaion Software Pack though it was within my means to use any other RDBMS Database.
Which Database does your Organisation use for your Node.JS Software Application’s Back-end
Currently, Node.JS Biometric Fingerprint Authenticaion integration module software pack retrieves Biometric Data and User Particulars for Biometric Fingerprint Authentication from MySQL in the Server Computer. This is so for ease of demonstrating the Node.JS Biometric Fingerprint Authentication features and their functionality otherwise you can chose to use any other supported Database for your Back-end as is deemed necessary by your organisation
Prerequisite for Running NodeJS Biometric Fingerprint Authentication Software Application PACK
You will need to pre-install the following npm modules;
- express – This will allow you to serve your Node.JS remotely among many other functions it performs. Think of IIS or Apache web server here. If you have an existing Node.JS software application chances are that you already have it installed.
- path – This helps you work with directories paths and file paths.
- body-parser – This gives your Node.JS application capability to unzip incoming data objects served from server side.
- route – This helps you handle route patterns and http (https) requests.
- mysql – This module helps you connect to a MySQL database and handle CRUD operations in a MySQL Database table.
How to Register User Particulars and Enrol Biometrics Data in Node.JS App
The following steps demonstrate how to use Capture User Particulars and Enrol User’s Biometric Fingerprint Data for Saving to Jomutech Database while running Node.JS Biometric Fingerrint Authentication Software Application
- Copy to a path of your choice in server ( or computer)
- Identify path in your server where you have saved your Node.JS Biometric Fingerprint Authentification project sources e.g. C:/PERSON AUTHENTICATION NODEJS/
- Open Command Prompt. For Microsoft Windows I usually say open CMD. Get CMD.exe up and running.
- Change directory to where you coppied your Node.JS Biometric Fingerprint Authentification project sources e.g. CD “C:/PERSON AUTHENTICATION NODEJS/” You should now be able to see all your source files and directories including the BioAuth.js file
- At the command prompt, type node BioAuth.js to run NodeJS Biometric Fingerprint Authentication software application.
- In your CMD prompt you should be having something like C:/PERSON AUTHENTICATION NODEJS/node BioAuth.js
- Press Enter to run NodeJS Biometric Fingerprint Authentication software application.
- If all goes well, you should see the server listening on port 8000. If you had remembered to install the prerequisite npm middleware and modules mentioned above you should see something similar to the below. C:/PERSON AUTHENTICATION NODEJS/node BioAuth.js Server Listening on port 8000
. . . . . . . . . . . . . . If you have reached this far without encountering any caveats you are catching up very well! Thumbs up!
I will now show you how to run NodeJS Biometric Fingerprint Authentication software application on Web Browser i.e. on the Client Side now that we have seen that the server side of things is already up and running.

How to Authenticate Enrolled Biometric Fingerprint Data in Node.JS
The following steps will show you how to do Biometric Fingerprint Authentication in Node.JS
1. Open Internet Explorer Web Browser and at the address bar type below web address
if running on LOCALHOST
if running from a remote server
http://[YOUR SERVER IP]:8000/nodejs/biometric/fingerprint/authentication/
if you have enabled HTTPS on your server, do not forget to run
https://[YOUR SERVER IP]:8000/nodejs/biometric/fingerprint/authentication/
You should now have something like the following after you open Node.JS Biometric Fingerprint Authentication Page. See below
2. Proceed to perform Node.JS Biometric Fingerprint Authentication tests by touching Fingerprint Reader / Scanner then observe what happens thereafter.
3. If a Fingerprint is Enrolled, you should get an alert that retrieves User Particulars i.e First Name, Second Name, Employee Number. Depending on what you chose to display or how you decide to do your integration you can decide to display retrieved data of SUCCESSFULLY authenticated person or do something else. See below for displayed data of Biometrically Authenticated User in Node.JS
4. When a Person does NOT Exist in the Node.JS Biometric Fingerprint Authentication Database or a wrong Finger is used for Authentication, the Node.JS application will notify you about it and return an Employee NOT Found message and also prompts you to Use Correct Finger for Authentication.
Note: There will be no user data to display as the back-end authentication process running on the server did NOT FIND A MATCH in Database for presented finger.
Sometimes the NETWORK acts up and the MySQL database server or the node.js server becomes unavailable. In the case of such eventualities, when you attempt to do Biometric Registration or Biometric Authentication with your Node.JS Biometric Fingerprint Authentication Software Application pack you will be notified about this eventuality with this message, Error My Friend. Check Jomutech Node.JS server side of things
