Editing Polymer banknote (section)

== Security features ==

Polymer banknotes usually have three levels of security devices. Primary security devices are easily recognisable by consumers and may include [[Intaglio (printmaking)|intaglio]], metal strips, and the clear areas of the banknote. Secondary security devices are detectable by a machine.  Tertiary security devices may only be detectable by the issuing authority when a banknote is returned.<ref>{{cite book|url=http://www.publish.csiro.au/nid/18/pid/6490.htm|title=The Plastic Banknote|author1=Solomon, David|author2=Spurling, Tom|publisher=CSIRO Publishing|year=2014|isbn=9780643094277|access-date=21 November 2014|archive-date=14 December 2014|archive-url=https://web.archive.org/web/20141214104602/http://www.publish.csiro.au/nid/18/pid/6490.htm|url-status=live}}</ref>
