Argentina: Securing voter authentication with biometrics

The authentication of voters is a first crucial step towards a legitimate election. This is why, around the world, authorities are relying on biometrics to maximize the transparency and efficiency of this process. According to International IDEA, as of 2016, 35% of more than 130 electoral commissions surveyed are capturing biometric data as part of their voter registration process.

In 2017, the National Election Chamber of Argentina selected Smartmatic to validate the identity of voters during the open primaries elections held in August and the legislative elections in October.

Authorities hired Smartmatic to furnish a solution that would enable poll workers to swiftly manage voter authentication in 6 Northern provinces (Chaco, Corrientes, Jujuy, Formosa, Misiones and Salta), and in 14 municipalities of the greater Buenos Aires.



This is Smartmatic’s all-in-one handheld device to facilitate ID management and polling station operation. Its biometric capturing capabilities allowed Argentinean poll workers to validate the identity of voters before they voted using real-time fingerprint comparisons with those stored in a database.

Identity Management System (IDMS)

Our IDMS was used as a central system to store and manage the biographic and biometric information of all registered voters. This system, which was synchronized with Argentina’s National ID database, was used to perform quality control and integrity checks. IDMS allowed the VIU-500 devices in polling centers to interface seamlessly with the database to authenticate voters with maximum accuracy and speed. The system also generated customized reports about voter turnout and other polling and status reports. This allowed officials to audit the processes for control and transparency.


Smartmatic provided the following services to the Electoral Commission:

  • Configuration and testing of all hardware, peripherals, software and data.
  • Training of field operators.
  • Technical support and field troubleshooting services at all levels.
  • Distribution and retrieval of equipment.
