Paper backup

Hi,

I have added a feature to egpg to export the key and convert it to 3D
barcode
images, included in a PDF file:
https://github.com/dashohoxha/egpg/blob/master/src/fn/qrencode.sh
This PDF file can be printed and used as a paper backup. It can be restored
with the help of a webcam and a barcode reader program (like zbar).

What do you think of paper backups, are they useful? I have seen some
advice that recommend them, and even claim that they are safer and
more durable/reliable than digital backups.
I think that lots of people are still familiar and comfortable with storing
and
keeping hard-copy documents safe and secure (although we live in the
digital age).

It could also be nice to generate a PDF page that has the gpg key
information
in the format of a business card: name, email, fingerprint (maybe in barcode
format as well). It can repeat several copies of the business card in the
same
page (for example in 5 rows and 2 columns).
Any idea or advice on how to implement this? Maybe starting with a latex
template and converting it to PDF? Or any simpler way?

Thanks,
Dashamir
