Hi,
I understood your interesting idea. I am interested to work on this. Just one change that would require is that Users have to connect chip via Wifi or Wifi-Direct instead of Bluetooth. Because at any given point chip can have one active Bluetooth connection. Also you would need android app which is compatible with Smart TV so it can show card given by Chip. On Chip, a progam probably (python script) would require to manage connections and send cards. Hopefully I explained correctly, we can discuss further.
I am ex-Microsoft employee and have 8+years experience in software development and customization usingwide range of Microsoft technologies (C#, ASP.NET, MVC,WPF, Window form, Sql Databases, Azure, Sync framework etc.), Mobile technologies - Android, Xamarin and server side language node.js and Golang.
About my previous work, you can visit my profile to see feedback from previous employer. Let me know, If you find me suitable for this project and share complete details. If you want more details, we can discuss over chat/ skype.
Regards,
Shashi Bhushan
