Marina payment system

Overview
TWI is a compact access and payment control unit designed for ports, campsites and resorts. It coordinates vehicle access, service payments and utility billing, and integrates with the TALLYWEB payment platform.

Key functions

• Access – open doors, gates and barriers
• Boom management – ensure only the permitted number of vehicles enter
• User payment – settlement for showers, washing machines, tumble dryers and similar services
• Billing – payment processing for electricity and water

Bom-in-bom-out
TWI implements a bom-in-bom-out mechanism that prevents additional vehicle entries on the same code before an exit is registered, avoiding multiple registrations of cars with one code.

Access control and cross-checking
Operates as a standard access control for doors, gates and barriers. Cross-checking across in/out booms enforces single-entry rules and prevents duplicate entries without exit events.

Electricity and water management
Electricity and water consumption can be monitored and controlled. Electricity may be sold in packages, enabling operators to recover charges; billing for electricity and water is supported.

Payments and communication
TWI is radio-controlled as part of the TALLYWEB payment system (radio communication is more reliable than Wi‑Fi). It supports user payments for services and integrates with TALLYWEB workflows for consumption monitoring and online payment via mobile devices.

Use cases
Intended for ports, campsites and resorts to control access, manage vehicle entries, handle user payments (showers, laundry) and bill utilities.
