Reading fingerprints from scanners and manage them from the web page is a nightmare to developers. CAMS offers the end-to-end online SDK or Web API solutions to our clients who can use our APIs to implement the web based fingerprint login, web based fingerprint attendance system and etc. Using our api, biometric fingerprint scanners or readers can be integrated with the web application through the simple javascript changes. It just needs couple of mins to integrate the biometric scanner with your web application. More details are shared in the below documentation.

You can develop you server with any language such as NodeJs, Python, Ruby on Rails, PERL, Hack, Erlang, XHP, Haskell, Go, R, Scala, C++, JAVA/JSP, .Net (C#/VB.Net) and etc. Server language is not a parameter for enabling fingerprint reader from your website. All the operations are handled at the Javascript code level.

This page is applicable for people who falls in the following requirements

1. If you are looking for fingerprint scanner to read the fingerprint from your website
2. If you are looking for fingerprint web site login
3. If you are looking for fingerprint attendance system at your website

Then you may need to refer the Web API for Biometric Attendance documentation.

Once the fingerprint scanner is plugged into the USB drive, the respective driver will be installed automatically. If it is not installed automatically, then while trying to capture the fingerprint from web page, it will return a error code which you can handle for dispalying error message on the page to download the driver file to install.

Following javascipt operations has to be called for their respective opeartions to be perfomed by the scanner.

1. Capture - return a json object with fingerprint template and PNG fingerprint image
2. Compare - returns the score from 0% to 100% between given two fingerprint templates

You would be provided the sample html file once the API is purchased, using which you can capture the fingerprint templates, display the images and compare the captured templates. This file can be modified according to your need and added with your own project.

Following the is the jQuery code snippet from the sample file.

var returnPNGImage = true; // returns PNG image along with the template. Setting it to false, returns only template
var apiKey="To be generated from CAMS API Monitor";

capture(apiKey, returnPNGImage);
...
compare(apiKey,temlate1,temlate2);

function onCaptureSuccess(data)
{
	var plainData = data;
	//write the program to decrypt if security key is set in API monitor for the scanner

	var scannerData = getScannerSuccessData(plainData);

	var template = scannerData.template;
	var pngImageContent = "data:image/png;base64," + scannerData.image;

}

function onCaptureFailure(data)
{
	var failureData = getScannerFailureData(data);
	var erroString = failureData.errorString;
}

function onCompareSuccess(data)
{
	var plainData = data;
	//write the program to decrypt if security key is set in API monitor for the scanner

	var scannerData = getScannerSuccessData(plainData);
	var matchingScore = scannerData.matchScore;
}

function onCompareFailure(data)
{
	var failureData = getScannerFailureData(data);
	var erroString = failureData.errorString;
}

function capture captures the fingerprint template and image. Once the capture is success then onCaptureSuccess event is getting triggered, otherwise onCaptureFailure is getting triggered. function compare comapares given two fingerprint templates and triggeres onCompareSuccess event with comparison score. API key should be passed to the function. This an can be generated from API Monitor
