Trying Swipecard update

I noted a recent email saying the swipecards example had been updated.

I’ve not used it before so thought I’d give it a go and so create a simple example. Unfortunately it doesn’t seem to work for me. All I did was create the default app and followed the usage notes

Can someone suggest where I’ve gone wrong?

I’ve posted the code that I created on github where the readme details the steps I took.

Thanks Chris
