On March 26 the Sonda team is celebrating its 30-th anniversary!

30 years ago a few like-minded people united in a group and decided to develop an unusual product - the identification system based on fingerprint.

New Sonda’s algorithms on FVC

Sonda submitted two new algorithms on the regular Fingerprint Verification Competition - the advanced fingerprint algorithm and the algorithm of palmprint identification. Results were published on July 14 for fingerprint algorithm and on July 18 for palmprint algorithm.

Sonda to meet the PF of Argentina

On July 13 the Sonda Technologies Ltd. specialists had a meeting with the Argentinian police delegation headed by Mr. Guillermo Berra, Deputy Minister and Auditor General of the Security Service of the Interior Ministry of the Buenos Aires province.

Time & Attendance Tracking

Time & Attendance Tracking

Time & Attendance Tracking System

The Time & Attendance Tracking System (TAT) is designed for objective tracking of working hours by recording time of arrival and departure of staff on the basis of human biometric characteristics - fingerprints.

How does it work?

TAT system records the time of arrival and departure of staff. When employee on entrance or exit puts his finger on the biometric sensor, the system detects it and records the time of passage. All these records are stored in the central server. Identification time is 1-3 seconds. On the base of e-Journal all kinds of reports are being formed on an operator's query such as total working hours, absence, tardiness, delays etc.

The system operates in standalone mode and does not require additional maintenance. It perfectly operates in companies of any structure or personnel amount. TAT System is fully independent from any company's staff intervention. None of the company staff can interfere in the terminal operation. None of them has access to database or results of identification. It is fully autonomous and associates only with the information system of the company’s personnel department. TAT terminals can also operate in standalone mode or as a part of a local network which includes distant departments of the company. The terminal screen can display personal messages for staff or official announcement.

Control of arrival/departure is performed only by fingerprints without using smart-cards, which excludes the possibility of transferring a card to another employee.

Objective data on staff arrival/departure time are being transferred via Internet to the central system which manages the entire company.

The system is built as a whole network for data acquisition to the TATS central server. The TATS server performs searching for duplicates on registering every new worker and communicates with the company’s central server.

TAT terminal

Time & attendance terminal contains two optical sensors separately for Entrance and Exit. On applying a finger to the corresponding sensor the system performs identification of employee and records his arrival or departure time. Due to special technology of the optical scanner and software the TATS terminal provides reliable and accurate identification for problematic fingers (dry or moist skin, the large number of folds or scratches).


Employee’s registration is performed in the personnel departments. All fingerprint templates proceed then to the central database where checking for duplicates is performed to reveal attempts of reemployment those who were dismissed for violations.


  • Objective and independent working time tracking.
  • Full autonomy and protection from any staff or management interference. Independence from company's information systems.
  • Operating solely on fingerprints without using smart-cards which excludes identification on someone else's card.
  • Accurate and reliable data on working hours for accounting and personnel departments. Lacking of accounting errors which are inevitable with manual operations.
  • Supporting of the multi affiliated societies structure of an organization with unlimited number of branches.
  • Transferring all the data to the central server via Internet.
  • Checking for duplicates to reveal repeated attempts of applying for a job for employees dismissed for violations.
