The transporter works by scanning the object/person to the point that all necessary information is obtained to reconstruct that person at another location.
Does it then destroy the “original”?
Why can’t you reconstruct multiple copies based on the information you have?
Good question. There was a story based on that very problem in Analog some years back.
It seems the company that developed the process sorta glossed over that point and neglected to mention that little detail.
Very expensive instant transport around the world, frequented by politicians, rockstars and captains of industry.
A copy would instantly show up in Hong Kong, London, or Sydney, and the original would be quietly "recycled".
Got kinda messy when someone finally spilled the (human)beans...
