The innovation of the RFID chip or the Radio Frequency Identification has been a critical piece of technology that has been around since the early/mid 20th century (est 1938). Functions of a radio frequency identification (RFID) tagging system involves a tag and a reader. When scanned, the antenna within the tag picks up the radio wave and sends a response back to the reader.

This technology is being used for both short range and also long range identification, in the short-range identification category, this innovation is used in practical applications like credit cards (pay wave, tap and go ect...), animal identification (domestic pets, farm animals). The long range applications of the RFID chip is used in aeroplanes to bounce back a

The chip can be designed to ergonomically fit into many different objects as best suited, for example i’ve noticed supermarket have started to role out new barcodes paper that includes the RFID chip inside of them so that when a customer who hasn't paid for their item walks out the front entrance the anti- theft scanner alarms and alerts which attracts security to shoplifters. The RFID chips can be much smaller then a grain of rice (as seen on picture on first page), to as thin as paper and as big as a large as a brick.

(just like no supermarket is going to put a RFID chip on a loaf of bread).

Historical development and design processes employed

RFID technology has been historically a critical piece of innovation that has significantly impacted the modern world, with the first use of the chip estimated to be developed in pre second world war period. The Germans,
