PISCES (Personal Identification Secure Comparison and Evaluation System) is a border control database system largely based on biometrics developed by Booz Allen Hamilton, Inc.
The PISCES-project was initiated by the Department of State, Terrorist Interdiction Program (TIP) in 1997, initially as a system for countries in improving their watchlisting capabilities by providing a mainframe computer system to facilitate immigration processing in half a dozen countries. Foreign authorities used the technology to watchlist and exchange information with the United States Department of State about suspected terrorists appearing at their borders. The information is used to track and apprehend individual terrorists, not for wide-ranging analysis of terrorist travel methods", according to US-government reports. It matches passengers inbound for the United States against facial images, fingerprints and biographical information at airports in high-risk countries. A high-speed data network permits U.S. authorities to be informed of problems with inbound passengers.
PISCES workstations installed throughout a country are linked by wide area network to the participating nation’s immigration, police or intelligence headquarters. The headquarters is provided with the automated capability to monitor activities at immigration points, evaluate traveler information and conduct real time data analysis.
Currently the PISCES-project falls under "The Terrorist Interdiction Program" (TIP), an ongoing programme of the United States Department of State. TIP provides all necessary software and hardware (mostly commercial and off-the-shelf, such as cameras and passport scanners), full installation, operator training, and system sustainment. Additionally, TIP assists with immigration business process improvement at ports of entry chosen for PISCES installation.
For FY 2007, funds requested will support significant enhancements to the existing watch listing system software in order to provide a fraudulent document detection capability, a biometrics search capability, and greatly improved name-searching effectiveness.
Starting in FY 2010 and onward to FY 2011, PISCES funding will be increased in what the United States Department of State considers "high risk" countries such as Afghanistan, Iraq, and Pakistan. A project to verify US visas via limited access to a US government database will go under trial in select outposts. 
Although PISCES was operational in the months prior to September 11, 2001 it apparently failed to detect any of the terrorists involved in the attack.
According to the US Department of State,
- TIP provided photos and travel history to Pakistan of three of the four July 7, 2005 London Metro bombers.
- Within one week of TIP's introduction, a ring of human traffickers were identified at Chiang Mai, Thailand.
- Hundreds of travelers have been interdicted in Pakistan on suspicion of using stolen passports.
- "... in terms of linking it to specific arrests, nothing that I have -- nothing that I'm aware of."
- INTERPOL: "... TIP will also assist the upgrading of INTERPOL's communications system to transmit fingerprints, photos and other graphics on a near-real time basis to and from a participating country’s INTERPOL National Central Bureau (NCB). INTERPOL data can then be imported into PISCES to expand the pool of suspects."
In 2003: "is currently being deployed in five countries and is scheduled for deployment in 12 more countries this calendar year. Arrests and detentions have occurred in all five countries where the system has been deployed."
In 2005: "Since 2001, twenty nations have been provided this capability"
Expected 2011: 31 
- Maldives. PISCES was deployed in Maldives at 0000hrs on 20th August 2013, replacing the border control system developed and installed by NexBiz of Malaysia.
- Iraq. FY 2007 NADR/Terrorist Interdiction Program funding is requested to support efforts to disrupt the travel of terrorists into Iraq by increasing the number of Iraqi ports of entry equipped with and capable of effectively operating the program's PISCES watchlisting system.
- Pakistan FY 2002 PISCES system has been installed at seven major airports of the country i.e. Islamabad, Karachi, Lahore, Peshawar, Quetta, Multan and Faisalabad airports. The system has provision to accommodate information on suspects from all law enforcement agencies like Immigration, Police, Narcotics Control, Anti-smuggling, and Intelligence Services. 
- Malta. Inaugurated 2004-05-05 by the Deputy Prime Minister and Minister for Justice and Home Affairs Dr Tonio Borg and United States Ambassador Anthony H. Gioia. PISCES is being provided by the United States at no cost to Malta, and assistance will include installation of the system, training of immigration officials on use of PISCES, and maintenance of the system. The overall U.S. assistance to Malta for this program is valued at approximately $US 1.5 million, nearly Lm700,000.
- March 2004, during his visit to Thailand, Secretary Ridge and I witnessed the signing of the Memorandum of Intent for Provision of a Terrorist Interdiction Program Border Control System. Under this Memorandum, the Personal Identification Secure Comparison and Evaluation System, known in short as PISCES, could be used to screen people passing through Thailand’s ports of entry, so that we may be able to detect suspected terrorists.
- In FY 2007, NADR/TIP funds will be used to expand operation of the program’s watchlisting computer system to additional ports of entry and provide for system software upgrades as they become available.
- Bangladesh: memorandum of understanding signed in May 2004, renewable agreement would be valid for five years. Relevant portions of PISCES will immediately become operational at the capital's Shahjalal International Airport and later expand to cover all land, sea and airports.
- Tanzania. The State Department’s counterterrorism bureau is funding the "PISCES" (Personal Identification Secure Comparison System) program to improve interdiction capabilities at major border crossings. While the program targets terrorist activities, it has implications for narcotics and other smuggling as well.
- Nepal. TIP funding will further fund activities to help Nepal control its borders, as border controls are not yet very advanced, through the installation of the U.S. Terrorist Interdiction Program’s Personal Identification secure Comparison and Evaluation System (PISCES).
- Cambodia. FY 2007 NADR Terrorist Interdiction Program (NADR/TIP) funds will be used to sustain a computerized system for collecting, comparing and analyzing traveler data to identify possible terrorists, and provide for software upgrades to the system as they become available.
- Philippines. In FY 2007, NADR/TIP funds will be used to expand operation of the program’s watchlisting computer system to additional ports of entry in the Republic of the Philippines, and provide for system software upgrades as they become available.
- Kosovo. FY 2009 NADR Terrorism Interdiction Program funding will sustain existing program operations and provide for software upgrades to program equipment. 
- Macedonia. FY 2007 NADR Terrorism Interdiction Program funding will sustain existing program operations and provide for software upgrades to program equipment.
- Ivory Coast. FY 2009 NADR Terrorism Interdiction Program funding will sustain existing program operations and provide for software upgrades to program equipment. "The Ivoirian Ministry of Interior, in cooperation with the United States, uses PISCES to enhance border security at its major airport and seaport." 
- On August 6, 2009 Ivoirian authorities detained Imam Abd al Menhem Qubaysi, a Hizballah spiritual leader and U.S. designated terrorist financier, at the airport upon his arrival on a commercial flight from Lebanon. Qubaysi, who lived in Cote d'Ivoire for a number of years, was denied entry at immigration and returned to Lebanon on the same flight through the use of PISCES.
