Residents over 17 are required to hold a KTP (Kartu Tanda Penduduk) identity card. The card will identify whether the holder is an Indonesian citizen or foreign national. In 2011, the Indonesian government started a two-year ID issuance campaign that utilizes smartcard technology and biometric duplication of fingerprint and iris recognition. This card, called the Electronic KTP (e-KTP), will replace the conventional ID card beginning in 2013. By 2013, it is estimated that approximately 172 million Indonesian nationals will have an e-KTP issued to them.
