Bank Indonesia issued Regulation Number 11/9/PBI/2009 to amend the specifications for the 100,000 Rupiah banknote issued in 2004, enhancing design elements such as signatures, issue year, and print year. The regulation details the updated physical characteristics of the note, including its red dominant color, imagery of the Proclaimers of Independence and the Parliament Building, and specific security features like optical variable ink and ultraviolet-reactive elements. Additionally, Article 5A explicitly declares that banknotes issued prior to this regulation remain legal tender provided they have not been revoked or withdrawn from circulation.
