Hi,
Don't think this tread is about piracy, that's not the subject at all !

To connect my bank web space, I've to use a small computing equipment where I need to plug my credit card in. Once plugged, this device computes some cryptographic challenge to generate a code I can use to connect the web site.

I just wonder if there is some way to develop an smartphone application to do the same. Of course, this application should know about the credit card. But I wonder if this would be enough to be able to compute the challenges the same way.

Any idea?
