What is NID?

The Bio-Metrica National Identification System - NID™ is a modular system that provides an end-to-end national identity solution. From securely enrolling and identifying citizens using biometrics and smart cards, NID™ is a scalable from small municipal or corporate implementations, to nationwide identification systems utilizing stationary and portable identification terminals to ensure citizens or employees are who they say they are.

All of this runs on the robust BII™ architecture, which allows collected information to be shared across multiple applications.

Why do I need it?

NID™ makes it easy to enroll and identify citizens using biometrics to verify their identity and provide a secure identity card based on AAMVA standards that can be used to verify identity in regions where an online system can be prohibitive. It provides a higher level of security by ensuring people are who they claim to be and are therefore entitled to whatever benefits, information, product, or service they are rightfully entitled to.

How does it work?

NID™ provides a set of functions that allow easy enrollment and identification of citizens:
  • Enroll multiple types of biometrics via a variety of devices from different manufacturers
  • Take a high quality picture that can be also used to identify a citizen via facial recognition
  • Maintain a strict log of data that has been entered in the system including enrolled citizens, and citizens that have been already identified at particular ports of entry
  • Keep detailed information of administrators performing verification of citizens and controlling access to system data via a multi-tiered access scheme
  • Provide detailed reports and activity logs of system users and administration staff to prevent abuse of the system
  • Flexible deployment on desktops, mobile systems, or hand held terminals for remote deployments

Who uses it?

NID is used by corporations, governments, and other entities which need a robust, secure system to enroll and identify citizens or employees. NID™ is a customizable system which can be adapted for any organization's needs.

The Enrollment screen is where all data on the citizen is entered in the system. The operator will capture all the information in a customizable form and then enroll the user's fingerprints (or other biometric types) and take several photos. Enrollment generally includes both demographic and biometric information including identification characteristics, a picture, name, address and identification documents (by default the system will use fingerprints, but the biometric method can be customized according to customer requirements). Enrollment can be configured in a way that it will not let the operator to save the information until a set of activities are established, such as high resolution fingerprints, minimum number of fingerprints captured, specific mandatory fields, high resolution pictures taken, immediate duplication search within the local database, and near real time duplication search for the entire database, etc.

Identification / Verification

After enrolling the citizen, NID™ makes it easy to confirm their identity. NID™ uses a variety of methods to identify and verify the identity of a citizen.

There are three types of searches that can be performed.

  1. Verification Search (1:1): An operator can enter biographical information for the citizen in order to locate the specific record.
  2. Identification search (1:N, 2:N, 4:N or 10:N): This method will take a fingerprint and compare it to all other fingerprints in order to find a matching record. In order to minimize the amount of records the search is required to go through, the operator can also enter some combination of a biographical plus biometric trait.
  3. Verification by ID Card (1:1): An operator will insert a citizen’s card into a card reader and the system will verify the identity of the citizen against the information stored on the care. This is the fastest method of citizen verification utilizing minimal system resources.

Out of the three, the ID card verification is the most efficient and utilizes the least server resources. It can even be designed to function in an area that does not have easy access to the centralized server.


While NID™ makes it very easy to enroll new citizen, there is always the possibility for people to try and take advantage of a system through the easiest way: Through Operators.

In order to ensure fraudulent data is not in the system, NID™ runs has two methods of checking newly entered information is both unique and genuine. Both of these searches are run nightly to check new records crated during the day.

  1. Biometric Duplication Search: This search method takes each of the enrolled biometrics and compares them against all of the previously enrolled records in the database.
  2. Biographic Information Search: The second search takes the biographical information collected during enrollment and performs a comparison against text entered in other records.

In the Investigations area, results from both of these searches are displayed, and combined to allow investigators to remove fraudulent records as well as identify individuals who are perpetuating the fraud.

Identification Card Management

NID™ can natively manage the issuance and retirement of ID cards used to identify citizens or employees. After enrollment of a new citizen, NID™ will automatically create a request for a new card and place it into a queue awaiting production. This only happens after operators have fully verified the citizen and all errors have been corrected.

Depending on the desired deployment method, card requests will be bundled and sent either to a 3rd party vendor for printing or to an internal print farm to be produced. From the ID card management window, an operator or administrator can track the exact production status of an ID card. Retired or fraudulent cards can also be removed from a citizen’s record from the management screen.

When a citizen obtains a card, operators can activate the card from the ID card management screen to ensure that cards which had been intercepted in transit are not fraudulently used before the identity of its holder is verified.


NID™ provides a comprehensive report generation mechanism. The operator can generate a report for all registered citizens, verified citizens, and duplicate citizens (fraud attempts) by many other parameters including fingerprint quality, address parameters, etc.

Administration / Dashboard

BII™ keeps a detailed audit log of all activity that happens on the system and can be accessed from the main BII™ system management module. This centralized management system also allows administrators to centrally configure all BII™-based applications.
