Overview
EWVM is an EWWD product demo for bilingual, mobile-first visitor management. Visitors register without an account, photograph an identity document, review OCR candidates, add a selfie and meeting details, and receive a signed QR pass plus a gate code. Reception and security verify, check in, issue a card, add notes, and check out the visitor.
Business Problem
Paper guest books are slow to search, difficult to report, and weak at controlling sensitive identity information. Reception teams need a faster arrival workflow, while security and management need authorized access, current on-site records, and traceable actions.
Implemented Solution
- Indonesian/English public registration without a visitor account
- KTP/passport image capture and OCR candidate extraction
- Visitor review and correction before submission
- Selfie, host, purpose, and scheduled-time capture
- Idempotent submission and same-site/same-day duplicate prevention
- Signed QR pass and site/date-aware four-digit gate code
- Reception search, identity comparison, optional arrival photo, card issue, notes, check-in, and check-out
- Private media storage, encrypted personal fields, identity fingerprinting, consent versioning, and rate limits
- Dashboard KPIs and CSV/XLSX reporting
Current Evidence Status
EWVM is a deployed EWWD product/demo. It must not be described as a facility client deployment until a named deployment and permission are available.
Technical Implementation Logic
| Layer | Choice | Reason |
|---|---|---|
| Application | Laravel + Inertia + React | Server-controlled validation with a mobile-first interactive registration flow |
| Administration | Filament | Reception, security, resources, reporting, and exports |
| OCR | Tesseract with manual fallback | Local extraction with required human review rather than automatic approval |
| Security | Encryption + HMAC fingerprints + private media | Protect raw identity information while supporting duplicate checks |
| Pass | Signed QR + gate code | Two verification methods for reception and gate operations |
Frequently Asked Questions
Does EWVM automatically trust OCR?
No. OCR candidates must be reviewed; authorization, encryption, consent, duplicate checks, and retention are separate controls.
Is it a live client deployment?
It is a deployed EWWD product/demo, not a named facility case study.
Next Step
Review your registration, consent, host approval, gate, badge, retention, and reporting requirements before selecting an OCR or access-control design.
