Architecture
App: React Native, built with Expo Bare Workflow
Communicates with the servEase backend over the standard API used by all clients
Local hardware access (NFC, printer) goes through native Android SDKs
NFC Reader
Used for scanning employee-cards for login, customer-cards to assign sessions and vouchers for checkout
Supported NFC types:
Type A/B-Card
MIFARE
FeliCa
ISO 14443 and ISO 15693
The app reads the card UID and looks it up against the database using the backend
Senraise H10P's built-in NFC reader is accessed via native SDK
Built-in 58mm Printer
Senraise H10P has an integrated 58mm thermal printer
Printing goes through native printer SDK
Used for: customer receipts, on-the-spot reprints
Device Management (MDM)
Managed via MDM (tbd)
Devices run in kiosk mode (locked to the servEase Go app, no access to general Android UI)
Used for remote provisioning, app updates, and locking down devices deployed at customer sites
Setup / Deployment
Provision the device via MDM (enroll, assign kiosk policy)
Install/update servEase Go through the MDM-managed app channel
Customer pairs the device with his tenant after first app startup with a connection code generated in servease Go Settings
Troubleshooting
Problem | Likely Cause | Fix |
|---|---|---|
NFC not detecting tags | NFC disabled at OS level, or tag not held properly on top of the device | Check NFC in system settings; ask customer to hold tag flat against the marked NFC area |
Printer doesnt give out paper clean | Wrong paper width used | Confirm paper roll is genuine 58mm |
