Ans1: RFID applications include tracking apparel and consumer packaged goods, tires, patients and personnel and currency and payment systems. In addition these systems enable business owners to have real-time access to inventory information. Tracking tags are also implanted beneath the skin of family pets.
In a typical RFID system, objects are equipped with a small tag which contains a transponder with a digital memory chip that is given a unique electronic product code. The interrogator, an antenna packaged with a transceiver and decoder, emits a signal activating the RFID tag so it can read and write data to it. When an RFID tag passes through the electromagnetic zone, it detects the reader's activation signal. The reader decodes the data encoded in the tag's integrated circuit (silicon chip) and the data is passed to the host computer for processing.
Ans 2: Implanting tags in apparel would be able to track individuals and would be able to list their belongings a consumer's name and credit card information with the serial number in an item of clothing. Tags in tires would enable the manufacturer to have access to information regarding where and when a vehicle is travelling.
The severity of the threat can reach extreme position by keeping track of your customers as well as of their belongings all the time. However it should be noted that RFID is also useful in some ways. For instance tracking currency has been appreciated by government since it prevents money-laundering, black-market transactions, and even bribery demands for unmarked bills.
Ans 3: In some cases it is advantageous such as in the case of a hospital when u can detect who was the major cause of the spread of a disease. However it also poses threat to privacy and the tags are constantly reading, processing, and evaluating consumers’ behaviors and purchases. In this way they would stop purchasing such products. On the other hand they are useful such as in implanting tags in things like explosives etc. Hence they should be used.
