I got a free card reader from Square. I was able to make an audio recording of the card data with it. From what I can see from the recording it shouldn't be too hard to decode the data from it.

Can you share the sample code or library to record and decode the data from Square credit card reader.

 

[Zeev Goldstein]

yes +1...
does this interfere with the voice on phone calls ?
as it is plugged to the earphone jack

Square credit card reader will be plugged into the earphone jack.

 

[Zeev Goldstein]

Yes, that is exactly what i said
Could you please share the code ?
Thanks

I get a cardreader from Chinesse supllier with SDK to read magnetic card reader but I need to do a wrapper to use with b4A

 

[Zeev Goldstein]

Yes but he said he overcame it by analyzing the audio he gets from msr
Interesting
Strange no one needed such functionality till now

hi
can you please send me the recorded audio file ?
how did you generate it ?
the reader is less problematic as i can buy it for about 1 USD
the issue is the software to support it
so i will appreciate if you could also send the code you used
you can use my private email zeev217@gmail.com
thanks

The Square card reader plugs into the headphone jack. You can make an audio recording of the data with any audio recorder. I used android recorder. I'm looking at the audio file on my PC with Audacity. The reader was free from Square and I'm just playing around with it now. I haven't wrote the code to decode it yet.

I'm still playing with it. I had to modify the reader to bypass the encryption chip but I got it to work with this: https://play.google.com/store/apps/details?id=me.cosmodro.app.rhombus.

You need to make wrapper from SDK factory this is only one way out
