When intangible information stands in for tangible physical authentication it needs additionally an identifier. The important thing we know about an exchange of value or transaction is that the transaction be authenticated in some way. Yet there is always some techno-fool seeing them as a way to be Hi-tech or Techno-cool with a double rabit ear finger curl.

Holding up your new super-car or luxury flat keys for a selfie to boast about your life style is known to be a stupid thing to do in this age of 3D printers.
