Public-education subjects
ICA’s public-education directory links practical advisories such as official-app use, e-Pass retrieval, anti-harbouring, biometrics and Special Pass explanations. Each advisory is a separate subject; select the relevant article rather than treating the directory as an application form.
Use the date and purpose
A rollout announcement explains an introduction at its stated time; an operational guide explains a current task. When both exist, read the live service instructions before making arrangements.
