Take a Windcave card payment

Overview

• Windcave is MiniTill's currently supported integrated card-terminal provider.
• A Windcave purchase has provider/session state in addition to the MiniTill Payment record. MiniTill persists enough transaction state to recover uncertain/interrupted attempts.
• The server-approved amount and remaining balance are authoritative; a terminal display alone is not sufficient reason to create a second payment.
• On native POS, certified Windcave flows include purchase recovery and the required signature/merchant-receipt handling where the transaction requires it.

When to use this

• Use Windcave when the configured POS device is linked to an active supported Windcave terminal and the customer is paying by card/EFTPOS.

Step-by-step

1. Confirm the correct POS device and linked terminal.
2. Start Card / EFTPOS payment once.
3. Let the terminal/customer complete the transaction.
4. Wait for MiniTill to show a definite approved, cancelled, declined/failed, or recoverable state.
5. If the result is uncertain, use recovery/status checking instead of starting another charge.
6. After approval, confirm the remaining order balance before any additional tender.

Common mistakes

• Do not press Card repeatedly because the terminal is slow.
• Do not switch register/store or start another conflicting payment while a Windcave session is active.
• Do not assume a customer was not charged just because the browser/app did not receive the final response.

Troubleshooting

• If the terminal is busy, resolve the active transaction/session before retrying.
• If MiniTill restarts or loses connection mid-payment, recover the existing Windcave session.
• If a terminal is unavailable in POS, check active status, provider configuration, POS-device assignment, and native capability.
