JavaScript Fingerprint Scanner API

Reading fingerprints from a scanner and managing them in the browser has always been painful for web developers. The Cams JavaScript Fingerprint Scanner API removes that pain: integrate a biometric fingerprint reader into your web application through simple JavaScript and build web-based fingerprint login and attendance in minutes.

Overview

Read and capture fingerprints from a USB scanner directly inside any website using a few lines of JavaScript — across all major browsers and Windows versions.

An online SDK and Web API that lets web applications capture and compare fingerprint images using client-side JavaScript, independent of the server language. Because all scanner operations are handled in JavaScript, you can build the backend in Node.js, Python, Ruby, PHP, Java/JSP, .NET, Go, and more. It powers web-based fingerprint login and attendance and is compatible with Chrome, Firefox, Opera, Internet Explorer, and Edge.
