You may still get your BM Exemption Number online even during your departure day. Use your smartphone and connect to the internet using mobile data (Connecting to the public Wi-Fi at the airport could be risky, as hackers might access your confidential information). However, suppose you’re already at the Immigration counter. In that case, the officer will refer you to the POEA Labor Assistance Center (LAC) for evaluation to determine if you may be cleared for departure or must submit additional documents.  To facilitate your departure, the LAC officer will encode your personal data, including your name, birthday, position, employer, and job site. Once you get the clearance, you’ll be asked to return to the Immigration counter for your final departure.
