RFID vs. barcode

By | July 3, 2009

Barcode.com: “RFID, or radio frequency technology, uses a tag applied to a product in order to identify and track it via radio waves. The 2 parts that make up the tag are an integrated circuit and an antenna. While the circuit processes and stores information, the antenna transmits signals to the RFID reader, also called an interrogator, in order to interpret the data in the tag. In contrast, a barcode is an optical representation of data that can be scanned and then interpreted. The data is represented by the width and spacing of parallel lines, and are often used in POS applications, in addition to tracking objects throughout the supply chain.” – The article goes on to give the advantages of both technologies. The more I read about RFID technology, the more interested I become. While the technology hasn’t really caught fire in health care, I think the utility of RFID demands further investigation.
