02 / 13Taximeter Main Board Engineering
The main board is the heart of a taximeter. Santim engineers it as a complete platform — measurement, secure recording, power and peripherals — designed to stay accurate in a vehicle that never stops working.

[The challenge]
A taximeter works through vibration, heat, cold and electrical noise, shift after shift. Every fare must still be measured correctly and recorded beyond dispute — for the driver, the passenger and the inspector.
[Architecture]
How the system fits together
Measurement core, secure memory, display and peripheral interfaces are designed as one validated platform, with a clear boundary between the parts that affect metering and everything else.

[Capabilities]
What we engineer
Protected fare records
Recording paths built so that stored fares cannot be changed without leaving a trace.
Automotive power design
Robust handling of engine starts, voltage dips and electrical noise in the vehicle.
Designed for manufacture
DFM-focused PCB layout and a long-lifecycle component strategy that keep production stable.
Quality and compliance
Development follows the controls expected of fiscal and metrological devices: documented design, controlled software versions and traceable production.
Integration
Printers, payment terminals, roof signs, fleet back-office systems and Santim SC-1 for the connection to the vehicle.
[Outcomes]
What changes in the field
- 01
Fares you can stand behind
Measurement that holds up for drivers, passengers and inspectors.
- 02
Fewer workshop visits
Robust hardware keeps vehicles earning instead of waiting for service.
- 03
Predictable production
A stable bill of materials over the full life of the product.
