I agree it's unlikely to be roll paper - typically the paper used is
standard printer. My point stands, and you are incredibly naive if
you are relying on the details not being printed out.

I find your paranoia amusing.
While I agree that I wouldn't enter my details on a website that
didn't support SSL, that's got nothing to do with my paranoia that my
CC details would be collected on the wire.
The obvious weak link is at the ends of the line, not the transmission
process itself. That's where any "huge increased risk " to "ordinary
people" of "identity and monetary theft - merely for the convenience
of the business" exists.

Actually, the front of the card typically contains the minimum
information you have to supply the business with in order for them to
process the transaction. As you're presumably already giving them
that, and typically such details are kept on file (as opposed to the
CCV number and possibly the signature) I don't see how much extra
information they are gaining.

Such as ringing up the vendor and giving the details over an
"insecure" line? Because I'm exposing my self to the tiny risk that
some one is listening in on the call to collect Credit Card details
for the convenience of not having to send them a cheque in the post.
