I would like a simple low-cost circuit designed that can read EMV smart cards while connected to a computer with Bluetooth. Maybe HC-05 module or HC-06? Looking to keep total component cost in the $5 range at quantities of 50 or more. Must be able to work with 3.3v or 5v smart cards.
PCB Size 3 x 2.5 Inches Vertical Height is longer side. 3 Layer PCB, through hole solder.
Here is the Windows test application that I use to read cards using a USB reader. Must be able to run on my computer with your design. Feel free to modify as needed and return.
