Muin Go Mobile App

Muin Go is a modular mobile app with 9 business modules: NFC tap-to-pay, in-kind donations, event check-in, expense capture, and field operations.

Muin Go is the modular mobile app (iOS and Android) that replaces separate field tools with one unified app. Your tenant login determines which of the 9 business modules are available. The Payments module turns your phone into a payment terminal, while other modules handle in-kind donations, event check-in, expense tracking, document capture, and more.

Offline Mode

How Offline Mode Works

When your device loses connectivity:

  1. The app switches to offline mode automatically
  2. A banner indicates offline status
  3. Work that does not need a live card connection is recorded locally
  4. When connectivity returns, that queued work syncs automatically

Card payments are the exception, and this is deliberate. Contactless card payments need a live connection to Stripe, so they are never queued — a queued card charge would be a promise the device cannot keep. Offline, a card payment is declined with a clear message rather than accepted and lost.

What queues and what does not

Action Offline behavior
Card / Tap-to-Pay payments Not available offline — declined with an on-screen message, never queued
Refunds Not available offline
Cash payments Recorded locally, syncs on reconnect
Check capture Recorded locally, syncs on reconnect
Quick-add donations Recorded locally, syncs on reconnect
Event check-in (roster, QR scan, NFC tap) Recorded locally with the real tap time, syncs on reconnect
Class time-clock punches Recorded locally with the real punch time, syncs on reconnect
Expenses and in-kind intake Recorded locally, syncs on reconnect
Invoice lookup Only cached invoices available
Transaction history Only locally stored transactions visible

Offline Best Practices

  • Ensure a full sync before going to an area with poor connectivity
  • Do not plan on taking card payments where there is no signal — collect cash or a check instead, both of which record offline and sync later
  • Monitor the pending-sync count and reconnect before the end of the day

  2. Remove thick or metal phone cases
