Modernized time-tracking for a Texas school district

We rebuilt the biometric time-tracking system for a Texas school district with new hardware and custom software, ensuring full compatibility with legacy fingerprint data and no data loss during remote deployment.

Client:
Texas public school district
Industry:

Problem

The existing time-tracking system relied on outdated hardware, and the original fingerprint scanner was no longer supported by its manufacturer. Moreover, the legacy software was incompatible with modern operating systems.

Challenge

The system stored tens of thousands of employee records and hundreds of thousands of fingerprint scans. The new solution had to recognize older fingerprint data so that long-time employees would not need to re-enroll; in other words, the update had to work seamlessly with legacy data.

100,000sfingerprint scans

Our Solution

We identified and tested a new hardware provider for touchscreen time clocks and fingerprint scanners, designing custom casings to fit the new devices. We developed new software that replicated all existing functionality and modified the device drivers to recognize fingerprints from the old system. In addition, we implemented a remote deployment mechanism to update all devices in the field without on-site intervention, ensuring a smooth transition with zero data loss.

Before and after

The main menu kept all five modules. Every module is active and the screen is easier to read.

What we built

01

Hardware

New touchscreen time clocks and fingerprint scanners, tested before rollout. Custom casings designed by our team.

02

Software

The BioScreen app rebuilt with all existing functions and a refreshed interface.

03

Legacy fingerprints

Scanner drivers modified so the new devices read fingerprints enrolled on the old system.

04

Remote deployment

Updates reach every terminal in the field without visits to campuses.

Terminal modules

Employees use the same five modules as before, on new hardware.
