When Radio Frequency Identification (RFID) became a requirement for suppliers of stores like Wal Mart Stores, Inc., organizations rushed to adopt the technology, which uses radio waves to track objects. However, companies should be careful in taking on RFID too quickly, as understanding how RFID works, how to gain ROI from RFID and whether it is the right fit for you is important for its success.

Radio Frequency Identification (RFID) is a technology that allows objects, animals and people to be recognized by radio waves and is increasingly becoming a popular alternative to the bar code.
In his introduction to RFID, Steve Winkler of the SAP Developer Network describes the technology in the following way: An RFID reader sends an interrogating question (e.g. "who are you?") to an RFID tag. The tag can then respond with an answer to the reader (e.g. I am product XYZ from company ABC). In this manner, similar to other sensing technologies, e.g. bar codes, RFID allows objects to be identified.
Here are some other quick notes about RFID basics:
- Radio waves can be transmitted directly through objects, so RFID readers don't require a line of sight to read the RFID tag
- The radio waves have a minute electrical current that is used to power the tags
- An RFID system consists of three components: an antenna, transceiver (often combined into one reader) and a transponder (the tag).
- Unlike bar codes, advanced forms of RFID make it possible to determine certain aspects of an object's physical state, such as temperature.
How is RFID used in the manufacturing industry? Manufacturing RFID can greatly increase efficiency and save time and labor costs by tracking items as they move throughout the supply chain.
However, it's important to build a business case for RFID and assess if it's the right fit for your company, as Virgin Atlantic did with a pilot program for using RFID to track airplane parts.
In her guide to building an RFID business case, Charna Mamlok addresses some of the following questions:
- How do you choose the right RFID software vendor?
- Will RFID benefit your business?
- What factors are holding up adoption of RFID?
- How do you calculate ROI of RFID?
