In collaboration with GA Technology Service Centre, we built a web-based attendance system complete with hardware integration targeted at card readers and controllers by ST Access Control System Corp.
The system is based on Odoo (formerly OpenERP) v7 packaged in a tiny, low-cost embedded Linux Single Board Computer (SBC).
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. ~ Wikipedia
Our software-hardware combo keeps integration optimized and allows our clients to hit the ground running with the system with no hitch or hiccups. We're also glad that we could help keep maintenance costs to a virtual zero. The system can also be customized to be integrated with an existing HR system as well, minimizing the need for staff to relearn and adapt to new HR interfaces.
