Construction and Rental Company rents tools and small equipment to the building and construction industry. They have over 10,000 items available for rent. All items are stored in a single warehouse. Items are stored in an equipment table in the company's data base with the item serial number as the primary key. Customers select the items they want to rent and the sales staff enter the item serial number into the system to generate a rental agreement. When items are returned, the serial number is used to record the return and the system calculates the invoice. Recently, the company has lost sales because they cannot find items in the warehouse. A physical inventory resulted in a write-off of 10% of the inventory due to lost or stolen equipment. PWC is recommending the company implement an RFID system to better track the equipment within the warehouse and at the point of sale/return. Describe the key design elements for the system including the hardware and database elements (example, RFID tags must be attached to each piece of equipment)
