We need a program for raspberry pi which will connect the retailer pos printer to itself and capture the receipt data (from a serial port) and save them as a plain text or JSON object. Once the data is being saved we will then format it the way we specify and then use this data to send it to our server, where it will be added to the user account.
This device will also have the capability of adding the NFC/Beacon module for the user interaction (tap of their phone), which then receives the receipt that initially saved.
The program needs to be written in c#. The successful candidate needs to be able to know c#, ASP.NET, RESTful API, programming with IOT and embedded os. You will also need to be familiar with agile methodology.
