Volt: Secure Document Storage for Passport, NID, TRC, Driving Licence

16 May 20264 min read

Passports expire. National IDs need renewal. Qatar QID, Saudi Iqama, US Visa — all have countdowns. Miss one by a week and you're paying a late fee or missing a flight.

Volt is Moneybag's encrypted document vault. Upload a JPG, PNG or PDF, and the app does three things:

  1. Stores the file in your private Firebase Storage folder (no one else, not even Dream Group, can read it).
  2. Runs AI OCR to extract name, document number, and expiry date automatically.
  3. Schedules two reminders — 30 days and 10 days before expiry — at 9:00 AM local.

Pre-built templates

  • Passport — international travel docs.
  • National ID (NID) — Bangladesh national identity card.
  • TRC / Residency — Qatar ID, Saudi Iqama, UAE residence, tax residency certificates.
  • Driving licence — local or international.
  • Utility bills — for KYC / proof of address.
  • Other — any document you want safe + searchable.

Security: how your documents are protected

  • Encrypted in transit with TLS 1.2+.
  • Stored at rest in Google Cloud with AES-256.
  • Files live under users/{your-uid}/volt/ — Storage Security Rules block every other user.
  • Optional PIN + biometric lock means even someone with your unlocked phone can't open Moneybag.
  • File size capped at 15 MB; only image and PDF types accepted at the rule layer.

FAQ

How many documents can I store?+

Up to 20 per account. Each file can be up to 15 MB.

What file types are supported?+

JPG, PNG, and PDF.

Can I download a document later?+

Yes — tap any document card → Download. The file streams from Firebase Storage with a signed URL.

What if AI OCR fails to read my document?+

Moneybag falls back to local heuristics (filename hints) and, ultimately, lets you fill the metadata in manually. Save still works.
