Bug #8951
Updated by Yalavarthi Thriveni 13 days ago
Overview
The POS system integrates with multiple peripheral devices:
Barcode Scanner
Weight Scale Machine
Receipt/Bill Printer
Cash Drawer
POS Agent Application (Device Connector)
The client's expectation is that store agents should not manually manage device connections. All supported devices should automatically connect after POS login and remain connected until logout.
Non-Functional Requirements
*Reliability*
Device connections must remain stable throughout user session.
Auto-reconnect should happen silently if connection drops.
*Performance*
Device readiness ≤ 60 seconds after login.
Weight retrieval ≤ 1 second after placing product.
*Logging*
Capture logs for:
Device connection
Device disconnection
Print failures
Cash drawer failures
Scale communication failures
Barcode scan failures
*User Experience*
No manual device management.
No Agent Office dependency.
No repeated reconnect operations.
Seamless checkout process.
