Radio Frequency Identification (RFID) is a wireless system made of tags and readers. The reader, connected to an antenna, sends and receives signals. The tag uses radio waves to signal its identity to the reader. Tags can transmit up to pages of data that can be used for a wide variety of things such as theft protection, inventory tracking, race timing, and access control. RFID was first used in 1940 during World War II in order to identify friendly and foe aircrafts. Over the next few decades the technology slowly progressed until the 21st Century where it became integrated into many fields.
How It Works:
There are two different types of RFID tags: passive and active. The passive tag is powered by the signal released by the reader whereas the active tag is powered by batteries and can transmit higher wavelengths and greater distances. These tags transmit signals back to the reader which can contain a vast amount of information. The reader is then normally connected to a computer that does something with the information such as identify stolen objects or take inventory of a business.
- Automation of many processes
- Efficient
Cons:
- Expensive
- Complex to install
Future:
In the future this technology will most likely be more advanced and included in more everyday processes. Entire inventory systems for businesses could run automatically with this technology.
