Effective from 26 January 2011, the Directorate General of Immigration introduced ordinary electronic passports (e-passport) for Indonesian citizens. The initial launch quota was set at 10,000 copies for the year 2011. Biometric passports were initially available only in three immigration offices: West Jakarta, Soekarno-Hatta, and Central Jakarta. but availability has widened since the first quarter of 2014, with ordinary electronic passports being issued in all immigration offices in Jakarta, Surabaya, and Batam. The electronic passports are available in 24 and 48 page versions (like non-biometric passports). The biometric chips are embedded within the back cover of the passports.
