What Are RFID Tags and How Are They Used? RFID tags are a type of tracking system that uses radio frequency to search, identify, track, and communicate with items and people. Essentially, RFID tags are smart labels that can store a range of information from serial numbers, to a short des...
Most RFID tags are passive, meaning that they contain no power of their own. As they pass the RFID reader, the reader’s energy activates the tag, enabling it to send its information to the reader. RFID tags can be “inlaid” or stuck to the item as a label. They can also be a h...
What Are RFID Tags? RFID Tags/Labels are also called RF tags and use a non-contact automatic identification technology, allRFID Tags/Labels have a unique electronic code, which is attached to the object to identify the target object; they are commonly known as RFID tags or smart labels. Mor...
Because RFID tags do not have a lot of compute power, they are unable to accommodate encryption, such as might be used in a challenge-response authentication system. One exception to this, however, is specific to RFID tags used in passports -- basic access control (BAC). Here, the chip ...
What are RFID tags? Originally invented in 1980 by Charles Walton, RFID stands for Radio-frequency Identification, meaning ituses a radio to transmit data. RFID systems have quite an interesting history. Its ancestor was used as a listening device for the Soviet Union just before the Cold War...

There are two common types of RFID tags:Active RFID tags: tags that have their own power source and can read in a range of 100+ meters. Active tags are used by companies where asset location or logistics improvements are important. Passive RFID tags: tags that don’t have a power ...
Simply put, RFID tags are labels that can store various data such as serial numbers, short descriptions, or even pages of information. Types of RFID Tags Generally, there are three main classifications of RFID tags. These are: Active tags Passive tags Semi-passive (or battery-assisted) ...
individual product represented by an RFID tag. Barcodes are a much cheaper alternative to RFID tags, however. While different from a standard barcode, quick response (QR) codes are also cheaper than RFID codes, but they require direct line of sight and may not be suitable for all RFID ...
Like UPC labels, RFID tags are often used to uniquely identify the object they are attached to. However, unlike UPCs, RFID tags don't need to be scanned directly with a laser scanner. Instead, they can be recorded by simply placing the tag within the range of an RFID radio transmitter....
