Group - Assignment Examplelike a barcode on a good in a store. The scarper contains a silicon IC (integrated circuit) chip and an antenna. This chip is supply with a programme containing the ingathering particulars e.g. size, date of manufacture and serial number. The data are fed in terms of (0s) and (1s). Average chips will carry about 9 bytes (Moscatiello, 2007). The chip does not have to be visible since it uses intercommunicate waves that are not affected by obstacles along the straight communication path. This chip is normally powered by an incoming wave and is able to receive and transmit radio signals. The RFID tag/chip has a unique address that makes it distinctive among others.There is a reader that is connected to an antenna for sending and receiving messages to and from the chip. The reader has a program that can generate a digital signal like who are you. The chip replies I am so and so. This message is usually in the form of an electronic ingathering code (EPC). T his communication is regulated by a communication protocol and software that relates data in the database to the data accredited from the chip. The user interface hardware is usually a computer that upon receiving communication from the chip, it shows a message to the user. This can be the product description, status i.e. expiry dates, product price, location or even unknown product.The software has other programs that help it initialize multiple goods read at the same time. It usually applies an algorithmic program to queue the goods for communication with the reader. The software helps reduce the chances of multiple recording or omission of goods in the system. The reader applies the designated software to control multiple signals of the same product due to reflections and weak signals due to distance and power.The whole system is similar to that of bar codes except that the RFID tag can carry more data, transmits data at larger distances, does not have to be visible on the produ ct, and the tag can receive and send
