Well, I offer "some 800 #" as a model that's currently in use and, by
definition, no less secure than what we have now.  No, I do not send
credit card info with 40 bit encryption.  Perhaps the development of
this had better come from non-US sources....

Intrigingly, I could however I could send it to by brother clear by
saying MC number:  "My age-3" "the last 4 digits of my phone number at
my last place*2+56" "Your age time the number of cats you have +2"etc,
etc...

But that's not practical for business use, as it uses shared encryption
numbers, as it were...
