If you really want human readable, it's better to chunk the data up into
3 or 4 digit groups. So, instead of Z05738521581, maybe
Z05-738-521-581. Or perhaps even better, Z05-7385-21-581 (just a hunch,
but I suspect varying the length of the groups makes it easier to read).
Even better might be base-32 encoding the value. Strings of digits have
an information density of about 3.2 bits/char. Base-32 is just about as
readable, but gives you 5 bits/char, so you end up with a few less
characters (which you still want to chunk into 3 or 4 character groups).
