![]() ![]() Read Range for the Readers or Interrogators: Within Contact – 10 Centimeters.General Frequency Range varies from 30 – 300 kHz.Primary Frequency Range varies from 125 – 134 kHz.The Low-Frequency RFID tags generally fulfill the following checklist So, let us know the types of frequencies that RFIDs work upon: The RFIDs are majorly divided into three types. It is these RFID tags that are attached to products in order to track them. ![]() RFID tags are the tags or labels that have the RFID chip installed in it. RFID is a small chip that contains data or information and uses radio frequency to transfer information. So, allow me to remind you again that there is a difference between RFID and RFID tags. Well, as discussed above, RFID and RFID Tags are two separate entities. Manufacturing Companies and Tracking Assets or Products Manufacturing Companies, Construction Companies, and Tracking Vehicles Thus, let’s see the difference between the two.Īn Active Tag has its own Battery, thus, always activeĪ Passive Tag needs to be in the presence of the Reader However, Battery-assisted Passive Tags are used less frequently in comparison to Active Tags and Passive Tags. This battery gets activated only in the presence of the Readers. Battery-assisted Passive Tags : The Battery-assisted Passive Tags consist of a small battery (Not full-fledged battery like an Active Tag).Passive Tags : The Passive Tags are small in size, have no batteries of their own, and instead uses the Reader’s energy source.Active Tags : The Active Tags run on their own battery, and transmit their own ID signal.While talking about RFID Tags, there are mainly three (3) different types of RFID tags: A Substrate – It is commonly a plastic film that firmly holds both the microchip and antenna.An Antenna – An antenna is required to read and transmit data for the READERS.A Microchip – This is an integrated circuit, and it stores all the required information, further processes the same when required.Saying so, RFID Tags consists of three crucial parts: When the tags are attached, a two-way radio transmitter, also known as READERS or INTERROGATORS, sends a signal to the RFID Tags and reads the information through it. Radio Frequency IDentification systems (RFID) work by attaching labels or tags to the products or objects. Since then, technology has been improving every year while making the RFID tag more efficient and affordable. They wanted to show how the RFID device can be useful in multiple industries such as transportation, security, banking, and medical industries. Later, on January 23, 1973, Mario Cardullo, an American inventor, patented the first RFID tag, which is known to be the start of modern RFID.īefore patenting the RFID technology, the device was demonstrated to the New York Port Authority and many other potential users in 1971. Germany and other nations would use this technology to identify if the aircrafts were friendly or of enemy regions. One of the early uses of RFID can be traced back to World War II. It varies from a range of few centimeters to over 20+ meters. Though the function of RFID is similar to Barcode, to identify and capture product data, the difference between the two is, the RFID tag does not need to be within the line of sight of the RFID reader. RFIDs are frequently used for all sorts of products, from pharmaceuticals to warehouses, clothing, and accessories to transportation and logistics. The RFID tags are imbibed by a small chip that can receive and transmit information through electromagnetic fields. ![]() The objective of RFID is to track and identify objects or products through tags. ![]() Radio Frequency IDentification is commonly known as RFID.
