QR codes can handle 2953 bytes of 8-bit binary data.

That's not a whole lof of data, for full contact information plus
an OpenPGP key. It's unrealistic to assume a whole key will fit.
Luckilyk, the PGP keyserver networks work pretty well, and
there's other ways of distributing the keys, too. You can,
for example, provide a URL to the public key.
