Posjs is a web based POS (Point of Sale) container and hardware bridge. In this version we use Apache Cordova platform to allow building of native mobile applications using HTML, CSS and JavaScript.
We use a tcp socket cordova plugin to extend javascript environment with objects. That objects are used to access hardware-specific features like printing and scan text codes with HID USB devices.
The above figure shows a possible deploy of the system. Firstly a raspberry pi connected with compatible devices (printer EPSON TM-T20II, barcode scanner MJ_tech V3.00, magnetic card reader model MSR100 and Epson compatible cash drawers). In this node we execute The Server, that implement a TCP slave and contain drivers to allow communications with compatible devices. On the other hand we need a tablet with Android. We provide a Apache Cordova based SDK that allow building mobile applications using web development technologies.
