What is RFID?
RFID stands for Radio Frequency Identification.
How does an RFID system work?
In the most basic scenario, a reader connects to an antenna which sends a radio signal across a narrow band of radio spectrum. This radio signal communicates with a tag to identify the product the tag is attached to. This tag information can be used for identification or other solution activities. Antenna and tag selection will vary based on solution environment and need.
Are there any health risks associated with RFID and radio waves?
No, commercial RFID applications are under FCC Guidelines which incorporate safety standards for human exposure.
Why is RFID better than using bar codes?
Among other advantages RFID does not require a direct line of sight, enables multiple reads simultaneously and has built-in serialization.
Will RFID replace bar codes?
RFID and Barcodes can completely replace or compliment BarCode systems. The EPC (UHF RFID) encoding standard is based on the existing UPC system.
Is RFID new?
The predecessor to RFID was used in military applications in World War II. The first commercial use of RFID was in the early 70's. The current UHF standard used in most inventory applications was developed in the late 90's
