The thing is that sometimes you just need a cheap physical medium you can give away. Sure cloud is an alternative, but it's a bad one, since it costs money to keep online. A CD or a floppy is something you record and forget. And USB sticks are much more expensive and can be a security risk.

Apparently faxing is the preferred medium of exchange in the medical field.

One would think that some sort of common EDI would have come around by now.
