RFIDs are computer chips that can track their own location and wirelessly send data to receivers. They are extremely small: about the size of a grain of sand. RFIDs can send information to companies about the popularity of their products, and how long it takes the store to replace them. RFIDs can prevent shipping screw-ups, so that incorrect shipments can be determined before they are unpacked. LCD price labels fluctuate with inventory levels that ore determined through reading the number of RFIDed packages. RFIDed DVD packages can be read by a kiosk that will show the movie trailer. Kiosks can print price tags for produce based on size, color, and shape, and give information about products like wines. At the exit, a scanner can read the tags in the customer?s cart and debit that person?s bank account directly. RFIDs can also help in banks. RFIDs in your shoes can give your account information to the teller before you step up. RFIDs can also be invasions of privacy. For example, burglars can use RFID readers from outside to preview the contents of your closet that have RFIDs woven into the fabric. A middle ground would be for the store to kill the tags as you walk out the door. |
