Status tracking is a method of accurately locating an object in transit from point A to point B using a decentralized and digital location like a laptop or smartphone. The tracking information may be accessible from a variety of locations across the world to see where packages, freight, and items are now located, as well as other details like the order date, order number, ship carrier, final location, transit time, projected date, and proof of delivery. For example, for its customers' orders, Amazon.com, the world's largest online retailer, uses status tracking and numerous competing carriers. When you first place an order, Amazon.com sends you an email confirming the final pricing of all items, including the price of each item, the shipping cost, the shipment method, and the projected delivery date.
