RFID stands for Radio-Frequency Identification. It is a technology that uses electromagnetic fields to identify and track special tags that are attached to various types of objects. RFID technology is used in many different industries because it is a simple and affordable option for tracking all sorts of different things.
The RFID system is made up of a radio receiver and transmitter, and then the radio transponder. When the transponder is hit by an electromagnetic pulse from the transmitter, it will activate and transmit the pre-programmed data. In most cases, the transponder will reply back with its own custom inventory number. The radio reader can then take that data and analyze it into a computer system.
There are many uses of RFID technology. One of the most common is for use in manufacturing and warehousing. Each piece of inventory is tagged with a transponder that has a unique number associated with it. Then RFID radio transmitters and receivers can be placed in various areas of the facility where tracking information is needed. For example, in a warehouse, each item that is stored can have its own RFID transponder. When something is needed off a shelf, a robot can go scan for that RFID transmitter to quickly locate the item so that it can be retrieved.
RFID tags are a big improvement over things like barcode systems. This is because RFID technology does not require a line of sight connection to work. This allows the RFID transponders to be embedded in different objects rather than having to be printed on the outside of them. By having the transponder placed inside of objects, it allows them to be much more durable and long-lasting.
Just about every industry has great ways to use RFID technology to improve the way things are done.
