RFID has rightfully earned its reputation as a technology for efficiently tracking large numbers of items. This capability has become increasingly important in dealing with post-COVID supply chain issues. But what is an RFID tag, and how do they work? To understand RFID tags, it is first impo...
RFID is used to tag things with unique identities. An RFID tag microchip can be used for things like tracking store inventory, keeping track of equipment in a large and busy facility, creating automatic payment passes to allow people to go through tolls, and so forth. A small burst of ...

What is Passive RFID? Primary Frequency Ranges: 860 - 960 MHz Passive RFID Read Range: Near Contact - 25 Meters Average Cost Per UHF RFID Tag: $0.08 - $20.00 Applications: Manufacturing,Pharmaceuticals,Tolling,Inventory Tracking,Race Timing,Asset Tracking,Supply Chain Management,IT Asset Tracking,...
Tag collision occurs when many tags are present in a small area; but since the read time is very fast, it is easier for vendors to develop systems that ensure that tags respond one at a time. See Problems with RFID for more details....

Semi-passive (or battery-assisted) RFID tags: There is the emergence of a third type of RFID tag, a hybrid type known as semi-passive (or battery-assisted) RFID tags. These tags consist of a power source, usually a battery, in a passive tag configuration. What this means is the batter...
RFID tagging is somewhat controversial, as tags can theoretically be cloned or used for illicit tracking. Another concern is that RFID tag data can be read by anyone with a compatible reader. Additionally, tags can sometimes be read after an item leaves a store or the supply chain. Tags can...
RFID tags are made up of an integrated circuit (IC), an antenna and a substrate. The part of an RFID tag that encodes identifying information is called the RFID inlay. There are two main types of RFID tags: Active RFID.An active RFID tag has its own power source, often a battery. ...
Radio Frequency Identification (RFID) is a type of passive wireless technology that allows for tracking or matching of an item or individual. The system has two basic parts: tags and readers. The reader gives off radio waves and gets signals back from the RFID tag, while the tag uses radio...
