Hi folks,

what do you people think about connecting a Smartcard-reader to the i2c interface? This would allow smartcard based authentification for e.g. gpg or ssh (and possibly to lock/unlock the whole device). The FSF fellowship smartcard is likely a good point to start and since most (if not all) necessary software is already available for linux/ARM it's rather the hardware implementation that need's to be done. There are several cheap and small serial card reader modules available and I presume it wouldn't be too much work to somehow attach a reader to the Jolla's i2c bus and stick a selfmade (3D-printed) TOH around it...
I'm not too much into hardware engineering (actually not at all), but I just wanted to bring this one in and I'm curious to hear your thoughts!

Thanks in advance,

Chris
