We have many different projects relating with mag-stripe information using motor controllers or audio to encode the mag-stripe data. In this project, I will explain how I modified a Bluetooth Spinner Speaker to make mag-stripe payments with it. Initially, I designed a project called BlueSpoof: https://salmg.net/2017/06/13/bluespoof/ Which could be used to make payments with mag-stripe data using a Bluetooth speaker board. Its library ViolentMag could be used to generate magnetic stripe data using audio. So I will implement the same library and methodology for this project.

This a PoC of this project!

    - Connect to the Bluetooth spinner and approach the spinner to the card reader
