　　The long lines at the checkout at the grocery store are perhaps one of the biggest complaints people have about shopping. But before long, those long queues may disappear as the Universal Product Number (UPC) barcode is replaced by smart labels, also known as radio frequency identification (RFID) tags. An RFID tag is a smart bar code that tracks and reports to a web system every product you put in your shopping cart.

　　Imagine you go to the grocery store, fill up your shopping cart, and walk straight out the door. You no longer have to wait in line for the cashier to scan everything in your car one by one. Instead, these RFID tags will be connected to electronic readers that can instantly detect every item in the car. These readers will in turn be connected to a larger network that sends information about your purchases to retailers and product producers. Your bank will then be notified accordingly and the amount due will be debited directly from your account. All without queuing, without waiting.

　　RFID tags, a technology once used only to track cattle, are now being used to track consumer products around the world. Many manufacturers use RFID tags to track every product from the moment it's produced until it's taken off the shelf and thrown into a shopping cart.

　　In addition to retail goods, RFID tags are used to track vehicles, plane passengers, Alzheimer's patients and pets. Before long, they might even track your preference for chunky or creamy peanut butter. Some critics say that RFID technology is taking up too much of our lives - almost everywhere in our lives is affected by it.

　　In this article, you will learn what types of RFID tags are and how these tags track the entire supply chain. We will also focus on the non-commercial uses of RFID tags and how they are used by the Departments of State and Homeland Security. Finally, we will examine some of the human rights-limiting applications of RFID tags in what some critics believe are animals, humans, and our society.
