Câu hỏi thường gặp
What is a centralized guest profile database?
It is a unified, cloud-hosted repository that aggregates guest stay history, contact details, and preferences from all properties in a hotel chain to create a single, comprehensive guest profile.
Why is middleware better than migrating to a new PMS entirely?
Migrating to a new PMS is expensive, takes months, and disrupts front-desk operations. Middleware costs up to 80% less, implements in weeks, and allows staff to keep using their existing familiar local systems.
How does the system merge duplicates if names are spelled differently?
The system standardizes phone numbers into international formats and uses fuzzy-matching algorithms (like Levenshtein distance) to cross-reference similar names and merge them under one Master ID.
How does capturing LINE IDs help Thai hotels?
Since LINE is the dominant communication channel in Thailand, capturing a customer's unique LINE ID provides an absolute identifier that makes automated profile matching highly accurate while bypassing name-spelling errors.
Does consolidating guest data comply with Thailand's PDPA?
Yes, centralizing guest records actually improves PDPA compliance. It provides a single point to manage guest data consents, enforce encryption, and process right-to-be-forgotten requests across all properties.
