I think if people have the funds to buy a more or less expensive smartphone they can probably invest in an additional consumer grade reader/writer (for offline usage) too. > P.S. Last but not least, we could send QR codes via email! ;-0 Which my idea avoids, i.e. using super über mega cool local postal services, to support our *hard working* local postmen, instead of globally supporting people with root privileges etc! :-D Remember even Russian authorities, according to reports from 2013, are using German typewriters now, which means, at least to me, that the smart Russians are using their postal service too, or couriers, instead of email. ;-) Regards Stefan -- NaClbox: cc5c5f846c661343745772156a7751a5eb34d3e83d84b7d6884e507e105fd675 The computer helps us to solve problems, we did not have without him. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
