Pair a Customer Display with POS

Overview

• MiniTill's supported CDS pairing flow is local: MiniTill POS mobile discovers MiniTill CDS on the store Wi-Fi and opens a persistent local WebSocket connection.
• One POS is designed to pair with at most one Customer Display. A Store can still have several independent POS↔CDS pairs.
• The paired display is saved on the POS device so the app can reconnect automatically after normal interruptions or app restarts.
• Live cart data travels over the local connection rather than being sent through a remote cloud round-trip for every button tap.

When to use this

• Pair once when installing a dedicated CDS next to a POS, then normally leave that pairing saved.

Step-by-step

1. Put the POS device and CDS device on the same local Wi-Fi network.
2. Open MiniTill CDS and wait until it says it is ready for a POS.
3. In MiniTill POS mobile, open Customer Display settings.
4. Choose Find customer display and grant local-network permissions when requested.
5. Select the intended MiniTill CDS from the discovered list and choose Connect.
6. Confirm the connection state shows Connected.
7. Leave the pairing saved so MiniTill POS can reconnect automatically in future.

Common mistakes

• Do not pair several customer displays to the same POS; the supported architecture is one POS to one CDS.
• Do not put the devices on isolated guest Wi-Fi networks that block local device-to-device traffic.
• Do not keep pressing Find while the POS is already successfully connected to the intended display.

Troubleshooting

• If discovery is unavailable, the installed POS build may not include the native discovery module.
• If discovery finds nothing, check local-network permission and make sure the CDS app is open on the same Wi-Fi.
• If the saved display moved to another network/address and will not reconnect, use Forget and pair it again.
