System Settings

The settings menu is the configuration hub of the terminal, allowing you to adapt the behavior of the PosFix application to the specific requirements of your point of sale.

Accessing the General Settings Menu

1. Press the More button in the bottom navigation bar
2. Select General Settings

Note

Changes made in this menu apply only locally, to the current device. If you use multiple terminals at the same location, you will need to repeat the configuration on each device individually to ensure uniform operation.

Language Configuration

The PosFix system allows quick interface adaptation for operators speaking different languages.

Option	Language
Română	Romanian (Default)
Русский	Russian
English	English

From the General Settings menu, tap on the desired language. The application interface will translate automatically immediately after tapping the new option, without requiring a terminal restart.

Display (Product Font Size)

This setting adjusts the text size for product names across all sales screens (grid, list, favorites, cart).

Option	Size	Usage
Small	12px	More products visible on the screen
Medium	14px	Balance between visibility and space (default)
Large	16px	Easy reading, ideal for small screens

In the General Settings menu, select the desired option by tapping. The change applies instantly across all screens.

Medium Font

Large Font

Recommendation

Use Large if operators work on terminals with small screens (under 6 inches). Use Small to see more products simultaneously on larger screens.

Hardware Device

Select the type of POS terminal on which the application is running. This setting automatically determines which hardware functions are available (built-in printer, built-in scanner).

Recommendation

Enable haptic feedback in noisy environments to tactically confirm performed actions.
