Kahero POS can only use weighted barcodes in the following formats: EAN 13 and UPC-A.

Embedded weight barcodes format should follow this pattern **AABBBBBCCCCCD**.

* **AA** - prefix, by which the system determines that it is a weight embedded barcode. It must be “20” or “02” for EAN-13 and “2” for UPC-A.
* **BBBBB** - this will be your item's Barcode (note that it has to be programmed as five digits, for example "10823" or "00010").
* **CCCCC** - the weight (quantity) of item in grams. For example "02050" = 2.050kg
* **D** barcode checksum

The below is a sample of barcode with embedded weight.

* EAN-13
