Smart RFIDs

Thank you for visiting and supporting Smart RFIDs. Most of us know about the barcode technology which has been tracking things for several decades. The problem with these is that they are meant only to be read, they are “dumb” in that they cannot communicate directly with external devices. Smart RFIDs (Radio frequency identification) are components of a system which involves the use of an smart tag applied to or incorporated into a product, animal, or person for the purpose of identification and also tracking – using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.

Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing a radio signal, and the other is an antenna for receiving and transmitting the signal. There are generally three types of RFID tags: 1) active RFID tags, which contain a battery and can transmit signals autonomously 2) passive RFID tags, which have no battery and require an external source to provoke signal transmission, and 3) battery assisted passive (BAP) for a much greater read range. Today, Smart RFIDs are used mostly in inventory tracking and management.
