Bin card differs from stores ledger because the bin card:

1. Bin card is a quantity record maintained inside the stores department, attached to the bin. 2. Stores ledger maintains both quantity and value and is kept by the cost accounting department. 3. The bin card thus records quantity only. 4. Recording value would duplicate the stores ledger function. _Source: ICAI BoS Inter Paper 3, Ch 2 "Material Cost", §2.3 ¶4_
