Read magnet card data with Square card reader

Solar2D General Questions/Discussion
1

I got a card reader from Square, and are wondering if it is possible to use the audio library to read and decode card data from magnet cards like credit cards, with the use of this card reader from Square.
If so, can anybody point me in the direction of some sample code.

I found some old but great documentation of decoding the card data.

Bumping this thread.

Has there been any movement on this? Has anyone been able to effectively utilize a magnetic card reader through the earphone jack on the phone?

Thanks

Does Square offer an SDK?

We are using an electronic payment company called TransFirst. They do not seem to have a SDK or any specific code related to the card reader itself. What we have received from them is how to post to their transaction payment gateway and all of the complexities that come with that process.

I guess my real question is, what support is there for the earphone jack to receive the magnetic credit card information, if any?

Corona SDK does not provide any.  Corona Enterprise and CoronaCards have the ability to native SDK’s.  I did a quick google and didn’t find any easy to implement native solutions either. It’s obviously possible, but Square may be doing all the math themselves to convert the sound waves coming in on the port to digital data…  It’ may not be an easy thing.

However, Apple seems to have built a card reader using the camera to snap cards for its ApplePay system.  I believe, they may have SDK’s to do that available in iOS 8.
