InStore App – Available Settings (v1.2.6)​

Important

All settings and options described here apply only to version 1.2.6 of the InStore App.
If you are using an older version, some settings may differ or may not be available at all.

DeviceId​

Shows the unique identifier of this device. Quote this ID when contacting support or managing a fleet. (Read‑only.)

DeviceType​

Displays the device model/type (e.g., terminal vendor and model). Useful to identify hardware-specific behavior. (Read‑only.)

IP Address​

Shows the current IP address of the device on your network. Use it when setting up network printing or firewall rules. (Read‑only.)

Base settings​

CashBoxId​

The CashBox the app is paired with. It links the app to the correct fiscal/payment configuration.

Unpair CashBox​

Disconnects the current CashBox to pair another one (e.g., when moving the device to a new store).

Refresh DeviceConfiguration​

This button updates your device with the current backend configuration without requiring an app restart.

End App​

Closes the app gracefully and persists configuration changes.
Note: Closing during an active process (e.g., printing) may interrupt that process, finish ongoing tasks first.

Terminal ID Filter​

Filters receipts and data for a specific terminal within the CashBox.
For advanced multi-terminal options, see Multiterminal Settings

Operation Mode​

Defines which features are available in the UI. Some options and sections appear or hide based on this selection:

  • Consumer – Customer-facing (receipt display/printing). Allows changing Print Delay, which is not available in Merchant mode.
  • Merchant – Merchant/admin. Cannot change Print Delay, but offers extra gestures:
    • Pull down on the QR code screen to show the receipt.
    • Pull up to reveal action buttons.

Use local configuration​

If enabled, local device settings override the backend configuration.

If disabled, the app follows centrally managed (backend) settings.

Note

Currently, this setting can only be configured by internal staff via the backend. Customers do not yet have the ability to change this setting themselves.

Once the setting is disabled and the app is restarted, the configuration stored in the backend will be loaded into the app.

This configuration can be applied:

  • Per device: A specific configuration for each individual device.
  • Per cashbox: A shared configuration for all devices connected to a particular cashbox.

App settings​

Enable NFC​

Enables receipt transmission via NFC.
Preview: This feature currently works only on fiskaltrust‑provided devices.

Enable running in Foreground​

Runs the app as an Android foreground service also displaying a notification in the Android status bar (when notifications are enabled in Android settings) and takes care that the service is run at all times.

When enabled it results in the following behaviour:

  • Even if the InStore App is not in foreground (e.g., the user is working with the POS app on the same device), it continues to run in the background.
  • The InStore App auto‑starts after device boot so no manual start is required after boot. This means even without ever starting the InStore App manually it will start in the background automatically and can process actions (like trigger payments or show receipts).

Printer settings​

Note

Some options depend on the selected mode.

Printers​

Shows all available printers (USB, Bluetooth, or Network). Select the one you want to use.

Defines the delay before an issued receipt will get printed automatically if the guest/customer is not receiving the receipt in another way like scanning the QR code with their phone, just accepting it by pressing OK or another method.

Default: 30s. Available only in Consumer mode.

Paper width​

Set the receipt width: 48 mm, 72 mm, or 80 mm.

Executes a simple "demo" test print to check basic printer functionality.

Enable Network Print Server​

Opens a network print server on port 9100 so other systems can print through this device.

Payment settings​

Note

The UI first asks you to pick a Payment method. Depending on the method, additional fields can appear.

Payment​

Select the payment provider to use on this device (e.g., Hobex ECR, Softpay.io, Viva Wallet, etc.).
After selection, provider‑specific options appear as needed.

Hobex ECR (example of provider‑specific fields)​
  • Hobex ECR TerminalId – The terminal ID assigned by Hobex.
  • Hobex ECR Password – The password for ECR integration.
  • Hobex ECR Host – Hostname or IP of the ECR endpoint.
  • Hobex ECR Port – TCP port of the ECR endpoint.
  • Test Communication – Checks connectivity with the configured ECR endpoint before going live.

Middleware​

Middleware URL​

The endpoint the app uses to communicate with the fiskaltrust Middleware.

Start Middleware​

Starts the connection to the Middleware using the configured URL.

Stop Middleware​

Stops the live connection (use before changing URL, switching networks, or during maintenance).

Danger Zone​

Factory reset​

Restores the app to factory defaults and clears all local data/configuration.
Use this when giving the device to a different store/location or if a clean setup is needed.

Best practices​

  • Keep Use local configuration off if you manage settings centrally — this prevents drift from backend policies.
  • After changing Middleware URL, tap Stop Middleware → update the URL → Start Middleware.
  • For Network Print Server, consider setting a static IP or DHCP reservation; otherwise clients can lose the printer when the IP changes.
  • For Hobex ECR, use Test Communication before going live.
