Bank Indonesia issued Regulation No. 12/8/PBI/2010 to amend the design and security specifications for the 2005 issue 10,000 Rupiah banknote effective for prints starting in 2010. The updated specifications change the dominant color to bluish purple, introduce new anti-counterfeiting features such as a tactile blind code, rainbow printing, and scattered dot patterns, and adjust the obverse signature layout to include a Senior Deputy Governor. All previously circulated notes retain their status as legal tender until formally withdrawn, and the regulation takes effect immediately upon publication.
