RFID is an automatic identification technology that identifies tagged objects by using invisible radio waves.
Radiofrequency identification or RFID technology is an emerging technology that gives businesses the freedom to receive, store and transmit digital information about their products, merchandise, vehicles and more.
RFID works on the same principle as microchipping your pets – information is stored on an RFID chip or ‘tag’ and when needed, that information can be extracted from the chip. This example is RFID working at a very basic level.
Easitag provides RFID Labels to industries that improve varied aspects of their business using RFID technologies.
Manufacturing
RFID, or Radiofrequency identification stickers, tags and chips can be used in production lines by being attached to a manufactured product. This gives the manufacturer the ability to track the progress of their products throughout the assembly line.
Warehousing
RFID tags can be used in a range of different ways when it comes to tracking goods through warehouses. RFID tags can be attached to almost any product making it easier to locate, identify and track products throughout the warehousing process.
What is Radio-frequency identification?
RFID is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data. Typically in an RFID system or a ‘reader’ as they’re sometimes called, will communicate with a tag, which holds digital information in a microchip. An RFID system basically consists of three separate components –
The RFID reader
containing the electronics to send, receive and interpret RF communications with tags.
The RFID reader antenna
or coil that broadcasts and collects the radio signals for the reader.
A transponder (tag)
has a microchip that contains information to uniquely identify itself, such as a serial number.
How RFID Works
As the tag passes through the electromagnetic zone it detects the readers' activation signal. The reader then decodes the data encoded in the tags integrated circuit (chip) and the data is passed to the host computer.
One of the key characteristics of RFID is that it does not require the tag to be seen to read its stored data; this means that a tag can be placed either inside or outside.
What type of information do RFID tags hold?
RFID tags/labels can be used to access far more item information than can be encoded into a barcode. So significantly more information can be associated to and travel with an item e.g. colour, place of purchase, date of manufacture, price, warranty expiry date, etc.
