rhombus to use a square mag car reader

Hi,

I discover this lib : https://github.com/sshipman/RhombusLib

there is also android demo here : https://play.google.com/store/apps/details?id=me.cosmodro.app.rhombus&hl=fr

this is to transform any android device into magnetic card reader using audio input port.
The small reader itself can be purchase for very few on chinese market.
I got one and load the apk form the playgoogle and this is working nicely.

Can anybody transform this lib into a basic4android library ?

Rgds
