Features of Bin Card

Bin Card is an important tool of material control used in the stores department. It records the physical movement of materials and helps in maintaining accurate stock quantities. The main features of a bin card are explained below:

• Records Quantity Only

A bin card records only quantitative information of materials, such as receipts, issues, and balance in terms of units, weight, or volume. It does not record the value of materials. This feature helps the storekeeper focus on physical stock control without involving pricing or valuation complexities.

• Maintained by the Storekeeper

The bin card is maintained by the storekeeper or stores staff. Since it reflects actual movement of materials, entries are made immediately when materials are received or issued. This ensures accuracy and reliability of stock quantity information at all times.

• Separate Bin Card for Each Material Item

Each type of material has a separate bin card. This allows individual tracking and control over every material item stored in the warehouse. It prevents confusion between different materials and ensures detailed monitoring of stock levels.

Bin cards are updated continuously after every receipt and issue of materials. This feature ensures that the balance shown on the bin card always represents the current physical stock available. It helps management make timely decisions regarding reordering and production planning.

• Kept at the Storage Location

A bin card is attached to or kept near the storage bin or shelf containing the material. This allows easy access for the storekeeper and enables quick recording of transactions without delay, improving storekeeping efficiency.

• Shows Physical Stock Balance Clearly

One of the key features of a bin card is that it clearly shows the physical stock balance at any point of time. This helps in monitoring inventory levels, preventing stock shortages, and avoiding excess accumulation of materials.

• Acts as a Tool for Inventory Control

Bin cards support inventory control techniques such as minimum level, maximum level, and reorder level. By observing stock balances, the storekeeper can initiate purchase action at the right time, ensuring smooth production and optimum stock levels.

• Helps in Physical Stock Verification

Bin cards facilitate physical verification of stock. By comparing the bin card balance with actual stock available, discrepancies such as pilferage, theft, wastage, or recording errors can be detected easily. This strengthens internal control over materials.

• Simple and Economical System

The bin card system is simple, economical, and easy to understand. It does not require complex calculations or skilled accounting staff. This makes it suitable for both small and large organizations.

• Supports Coordination Between Departments

Bin cards help in coordination between the stores, production, and purchase departments. Accurate stock information enables timely procurement and smooth production scheduling, thereby improving overall operational efficiency.
