In the Philippines, people book beach resorts through Facebook pages and Messenger, then send a deposit by GCash. Scammers copy a real resort's name and photos to make a fake page and take that deposit.

SentralID Trace checks a booking channel against an official source: the list of real resort Facebook pages published by the San Juan, Batangas Municipal Tourism Office. We turned that list into reviewed records for 13 resorts, with every detail traced to its source.

You give Trace what you have: the page link, a screenshot of the page, or your chat. Even a pasted link alone works, with no AI needed. Trace then:
1. compares each detail with the official records using fixed rules,
2. shows what matches, what doesn't, and what can't be proven (like who owns the GCash account),
3. picks one safe thing for you to check next, such as messaging the resort from its official page, and
4. updates your result when you report back.

Trace never says "safe to pay." It shows exactly what it checked and where each answer comes from.
