You are the auditor of Fenton Electronics Ltd., which has recently installed a computerized bar code system to record goods received, sales, and inventory quantities. The company is a retailer of electrical products.

1.

When the goods are received, the receiving department:

		either reads the bar code on the box containing the product or inputs the bar code number manually;
		manually inputs the number of items received (e.g., a box may contain 100 thumb drives) and adds the quantity of items received to the quantity of inventory recorded on the computer

2.

When goods are sold to a customer, the bar code of the product is either read or input manually, and the computer produces the sales invoice using the selling price of the product, as recorded on the computers standing data file. The quantity of items sold is deducted from the inventory quantity recorded on the computer.

3.

Periodically, the inventory is counted and these counts are compared with those on the computer. The inventory quantities on the computer are amended when significant differences are found.

4.

The system allows:

		details of new products and the selling prices of products to be added or amended
		inventory quantities to be amended from differences found at the inventory count
		special prices to be charged to customers (e.g., when the product is damaged or discontinued)

The main products the company sells are:

		slow-moving products, such as televisions, video recorders, digital cameras, and audio equipment
		fast-moving, low-value products, such as batteries, electrical and charging cords, and thumb drives

Which of the following are controls that should be incorporated into the computer system to ensure goods received are correctly entered into the computer by the receiving department? (Several choices may be correct.)

Check digit included in inventory bar code

Match of product code to inventory master file

Authorization of pricing changes

Reasonableness check on quantity entered

Restricted computer access to senior staff member
