Free 30 Days Trial
An alternative to the time-consuming and complicated fingerprint SDKs provided by scanner manufacturers. Touch N Go enables you to integrate fingerprint recognition technology in various types of applications with just four lines of code.

Simple and Intuitive API

The simple and intuitive interface allows developers to seamlessly integrate fingerprint identification into any application workflow.

Accurate Enrollment

Designed to work well with various kinds of fingerprints – dry, wet, old and/or damaged. The enrollment method is user friendly and ensures registration of only the best quality fingerprints.

Use Database of Your Choice

Provides system integrators the flexibility to select their choice of database (Oracle, MS SQL, MySQL Enterprise, Sybase, and IBM DB2, etc.)

Easy License Management

Touch N Go removes the burden of manually tracking licenses from your IT team and effectively reduces Server Deployment and Maintenance Costs.

Industry Leading Performance

A reliable solution that can be scaled seamlessly to support a large number of users and locations without any degradation in performance.

Supports Web Browsers

Seamless integration into any Windows or Web-based software and ready support for multiple web browser choices – Google Chrome, Mozilla Firefox, Internet Explorer.

Fingerprint scanners support

Fingerprint SDKs provided by scanner manufacturers have a low-level API and are designed to work only with their own fingerprint scanners. These fingerprint SDKs do not provide the flexibility to integrate scanners from other manufacturers into your application. You would need to completely re-write your application if you choose to integrate some other manufacturer’s fingerprint scanner using either the other manufacturer’s SDK or a third-party SDK.

Touch N Go eliminates the need to re-write your applications when you choose to integrate a different manufacturer’s scanner. Our fingerprint recognition SDK supports a wide variety of leading fingerprint scanners available in the market and works extremely well with dry, old, wet or damaged fingerprints.

Supported Scanners

Server & client component

Touch N Go consists of a server and client component which are deployed as windows service. The server component stores the fingerprint data of users and performs fingerprint authentication. Touch N Go is suitable for both desktop and web-based applications.

The client component of Touch N Go communicates with your application using HTTP protocol. It displays the interfaces for the registration and search methods. With Touch N Go, ready support is available for multiple browsers such as Google Chrome, Mozilla Firefox and Internet Explorer.

Multiple layers of protection

With Touch N Go, the server and client communication is secured with multiple layers of protection such as Secure Sockets Layer (SSL). AES 256-bit encryption is used to protect the biometric fingerprint data.

The server centrally manages fingerprint data for all users. This product is ideal for desktop based as well as web-based applications. Touch N Go supports both SOAP and REST API.

It also uses FBI Certified WSQ Algorithm & Biometric Data interchange and interoperability standards (ISO 19794-2 and ANSI 378-2004 standards).

Why should you avoid a low level fingerprint SDK?

While some manufacturers might claim to provide a fingerprint SDK that enables rapid integration of fingerprint recognition into your software system, it still has many drawbacks. With these low level fingerprint SDKs the developers are required to have a good understanding of the various crucial elements like exception handling etc.

Furthermore, a robust fingerprint matching server software will have to be developed and the fingerprint software also needs to be tightly embedded into your application. This creates the disadvantage that the host software will have to be recompiled with the fingerprint SDK each time any changes or enhancements are done to either the host application or the fingerprint SDK.

What our Customers say

I found our Account Representative to be very professional and responsive to what our Company was needing. He was a pleasure to work with and represented your Company, Bayometric, in a very positive manner. I only wish that most of the individuals from other Companies were like him and responded as promptly. I look forward to doing future business with Bayometric and my interaction with your company.- Anthony Anguiano, National Security Directorate, Pacific Northwest National Laboratory
