The POS interface is in Arabic; screenshots and button names are shown as they appear in the app, with English explanations.
Every product is either UNIT or WEIGHT. A weighed product sells a decimal quantity, and scale labels carrying the price or weight inside the barcode can be read.
1Create a weighed product
In the product editor choose “Product type: weighed”. The weight section appears: unit (kg or g), price basis (e.g. per 100 g), precision, min/max, and whether manual or scale weights are allowed.
The product editor: name, regular or weighed product, barcode, short code and category · Arabic interface 2Scale code (PLU)
Enter the code the scale prints inside its labels. It must be unique; leading zeros are ignored. A label whose code isn't in the products shows the red line “No product with scale code …” and nothing is added.

In Settings → Products & weight → Scale barcode: price-embedded or weight-embedded, prefixes (e.g. 20,21), total length, product-code length, value digits and decimals. The page explains the layout with an example and validates it live.

“Weight product rules” set the type automatically from the barcode, name or category (starts with, contains, regex…) with a fixed priority, and a “Test” button to try any value.

FAQ
The POS never guesses: the red line “Unable to determine the scale barcode …” appears and the cashier searches manually. Check the layout in Settings and test it with a real label.
