About this app

BelterBox is the companion app for Belter Stacks — modular, battery-powered smart parcel lockers with Bluetooth locks. Open your assigned BelterBox compartments directly from your Android phone, no physical keys or codes needed.

Belter Stacks are dynamically configured parcel lockers built from individual BelterBox units that stack together in flexible arrangements. Each BelterBox has a built-in Bluetooth smart lock that you unlock with this app.

Key features:

- Unlock BelterBox compartments with a tap — use your phone as a digital key via Bluetooth
- See your assigned BelterBoxes — view all BelterBox compartments you have access to in one place
- Signal strength indicator — see how close you are to a BelterBox before unlocking
- Warehouse mode — toggle warehouse/office mode for supported BelterBox compartments
- Secure authentication — sign in with your organization's Microsoft account
- Audit trail — every BelterBox unlock event is securely logged

How it works:
1. Sign in with your Microsoft account
2. View your assigned BelterBox compartments
3. Tap a BelterBox and press "Unlock" when in range
4. The BelterBox unlocks via Bluetooth — no physical key or code needed

Requirements:
