The multi-function reader

by GrabCAD
My thought was to use "what BB already has in use".

I modelled the LCD case around to " BB Transact by #David "

I used David's device as mag stripe reader and NFC, I think it has the right geometry to be detached from the core unit and used in bluetooth inside the room. When it is on the main unit it can be recharged.
On the back side we find the same base drawn by David

I don't know If I will win this challenge, but in case of 1st or 2nd place, I'll give 50% of amount to #David

I'll soon send other renders
