# Introduction ![Trust1Connector](/files/-L9hsctzmp-3T4Ulz9Og) ## 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 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
