VALIDATION PROGRAMME

First prove that it is better. Then prove that it survives.

A staged test programme for interaction quality, operational confidence and physical resilience. No testing results or approvals are claimed.

WORKFLOW VALIDATION

Compare conventional manual keypad entry, a pre-programmed professional board, Smart direct squad selection and Smart manual fallback.

FUTURE INTEGRATION CONCEPT · NOT CURRENTLY CONNECTED

One authorised event. Multiple compatible outputs.

In a future connected deployment, one verified substitution event could update the pitchside board, stadium display and broadcast system—subject to competition procedure and integration with each technology provider.
