🖥️
💳 POS System
Corporate POS Platform with Open API Structure

  • OAuth / Token Authentication
  • API Polling or Webhook Events
  • Agnostic to Windows Updates
  • Managed by POS Vendor
LOCAL INTERACTION: On-premises POS system at store location

☁️
🔐 BizPrint Cloud Authentication Layer
  • OAuth / Token Auth
  • API Polling or Webhook Listener
  • Secure, Non-PI Data Bridge
  • Centralized Audit & Visibility
CLOUD SERVICE: Hosted authentication and API gateway
Concurrent API Calls: Parallelize polling/webhook handling to process multiple orders simultaneously

☁️
🔄 Transform & Normalize
Data Mapper extracts and transforms fields

  • Convert incoming payload into Smartender schema
  • Validate and clean fields
  • Map: order_id, customer_id, server_id, table_number, order_type, status, timestamps, item details
CLOUD SERVICE: Serverless data transformation pipeline
Batching: Group smaller order payloads before transformation to minimize overhead

📄 File Generator
  • Pipe-delimited .txt file
  • Filename: TicketNumber + MMDDYYYYHHMMSS
  • Example: 39234004222025172205.txt
  • Fields: order_id, customer_id, server_id, table_number, order_type, status, created_at, completed_at, order_item_id, item_id, quantity, unit_price, modifiers, notes
CLOUD SERVICE: Automated file generation service

5
☁️
📤 SFTP Daemon
  • Push files to Smartender endpoint via SFTP
  • SSH key-based authentication
  • Include retry logic, logging, and rate limits
  • Audit trail for file creation and delivery
  • Queue unsent files with timestamped logs
CLOUD SERVICE: Managed SFTP transfer service
Rate Limiting: Queue-based throttling to maintain predictable delivery cadence
Monitoring: Cloud telemetry tracks queue size, delivery latency, and retry events

🎯 Integration Approach

Selected Path: API Extraction (Cloud-Enabled) – This provides a scalable, secure, and maintainable solution with centralized visibility and audit control.

Why Not Printer Emulation? Local/sniffer-based approaches require privileged OS access, break with Windows updates, create unmonitored attack surfaces, and aren’t scalable. They remove centralized audit control and may violate POS vendor terms.

Security & Compliance: Cloud-based solution ensures secure non-PI data bridge, SSH key-based SFTP authentication, and comprehensive audit trails. All processing timing and volume targets can be guaranteed with SLA support.

Executive Value: No-hands solution where BizPrint develops the API integration and FTPs files to Smartender units, which then complete the beverage dispensing journey.
