Re: User story
A scanner can behave like a fax machine now? How does it prove receipt?
The reasons why fax is still used is:
1. Sending and recieving happen live, in REAL TIME. Mail is not real time. The two endpoints are in constant comms back and forth during scanning, sending and printing. If the fax machine at the other end breaks, the sending fax knows this. Email has some way to alert of delivery failure but its not able to tell you the email never got to the users inbox because the disk failed after the smtap server accepted the message.
2. You get a status report printed by the sending machine that will let you cover your arse when the other side claim you never sent it.
In basic terms the fax machine is the digital (i doubt many analogue ones are left about) version of a live phone call, only with images. Email is what it allways have been, the electronic version of paper post.
There however is something the NHS can use to replace fax. EDI. Electronic Document Interchange is a well defined standard for doing this sort of thing over almost any link from morse code to email or direct as2 connections. However, it is typically used for ordering and invoicing of products so im not sure if it is fully suitable.
To replace fax, you must replace fax. Not squeeze something that does half a job into the same hole because its more modern. You need a direct replacement.
