The invention of the Barcode provided the world with a much-needed identification technique and kicked-off a new wave of automation that continues till this very day. But this wasn’t enough in terms of innovation and efficiency. The widespread use and deep research carried out on the electromagnetic spectrum produced another identification technique: Radio Frequency Indentification (RFID).
Trends are emerging in the Automation Industry as they try to become more efficient and safe. Some commercial trends are slowly finding their way into the Automation Industry such as cloud systems and mobile devices.
Radio frequency identification, or RFID, is a technology using radio waves to automatically identify people or objects. The most common usage is to store a unique number, which identifies the item, on a microchip attached to an antenna. The chip/antenna combination is called an RFID transponder or an RFID tag. This tag then transmits the identification number, and possibly other stored information, to a reader. The reader then supplies this information to a PLC system or directly to a computer via standard industrial communication methods; Ethernet, Fieldbus, etc.
