Valet QR Pro: system architecture.

A cloud-based B2B valet parking platform that supports vehicle registration, unique valet tokens, guest car requests, preparation status and claim verification.

Overview

What the platform does

Business Challenge

What required engineering

The workflow has to connect a fast mobile-first guest experience with valet operations, status changes and controlled vehicle handover without forcing guests through a complex app journey.

Engineering decisions

  • Keep the guest flow mobile-number-first and low-friction.
  • Use a unique non-repeating same-session/day token for operational clarity.
  • Treat optional vehicle/customer details as optional rather than blocking the core workflow.
  • Limit public architecture detail where deployment or security configuration is not necessary to disclose.
