## Introduction

This is a guide to use the T1C-Js client for the T1C-GCL (Generic Connector Library).\
Trust1Connector is a product of Trust1Team in order to facilitate browser independent hardware communication from a web application with an unmanaged device.\
The web application serves as a mediator in order to implement business flows. A web application stays in control for service requests towards a central back-end, and service requests with an unmanaged device.\
The Trust1Connector consists of:

* T1C-GCL (Generic Connector Library): an one-time installer for OSX, Windows, Linux
* T1C-DS (Distribution Service for T1C-GCL): a secured back-end in order to distribute and manage running T1C-GCL instances
* T1C-JS (JavaScript client library): an optional JavaScript client library in order to facilitate the communication towards T1C-GCL and T1T-DS.

Additional plugins (community and private plugins) are in development.\
Additional client libraries for native applications are in development.

## Characteristics of T1C-GCL

Because the T1C-GCL runs on unmanaged devices, the T1C-GCL has some important specifications:

* browser independent (no impact upon browser update)
* not in need of a browser plugin
* based on official communication standards
* no additional software needed (for example no need of a Java virtual machine)
* small footprint (+-2MB)
* coops with multiple card readers (contact and contactless)
* coops with multiple connected cards of different types
* extendable community framework 
* installer compiled for OSX, Windows, Linux
