What does the bar code on the back of the Lego minifigures do?

The barcode on the back of LEGO minifigures is primarily used for inventory and tracking purposes by retailers. When scanned, it helps manage stock levels and sales data. Additionally, some collectors use these barcodes to identify specific minifigure series and characters. However, the barcode itself does not contain any unique information about the minifigure beyond retail functions.
