There are certain differences between RFID and Beacon. When most people that they’re both working the same, Beacon and RFID are different thing.
RFID stands for Radio-Frequency IDentification. The acronym refers to small electronic devices that consist of a small chip and an antenna. The chip typically is capable of carrying 2,000 bytes of data or less.
While a beacon is an intentionally conspicuous device designed to attract attention to a specific location.
Beacons can also be combined with semaphoric or other indicators to provide important information, such as the status of an airport, by the colour and rotational pattern of its airport beacon, or of pending weather as indicated on a weather beacon mounted at the top of a tall building or similar site. When used in such fashion, beacons can be considered a form of optical telegraphy.
RFID itself divided into two parts: passive and active.
A passive tag is an RFID tag that does not contain a battery; the power is supplied by the reader. When radio waves from the reader are encountered by a passive rfid tag, the coiled antenna within the tag forms a magnetic field. The tag draws power from it, energizing the circuits in the tag.
Active RFID tags have a transmitter and their own power source (typically a battery). The power source is used to run the microchip’s circuitry and to broadcast a signal to a reader (the way a cell phone transmits signals to a base station).
Industry has been using RFID for so long. It also has disadvantages such cost operational that’s expensive and short lifetime battery. Which is why some industries are changing to beacon.
The cost is also pretty affordable for industry usage while other cost pretty high for devices. With multi benefits, a beacon usage can be safer and easier to maintain than other devices.
