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.

RFIDs and the Parts They Play in Enterprises

For a business to become truly competitive and highly efficient, it should learn to adapt with a variety of changes. One of these will be the use of technology to ensure the security of their data and to administer proper flow of operations. You can get all these and more with an RFID, or radio-frequency identification card.

Defining an RFID Tag

A tag that is considered to be an RFID will be something that you can attach to an animal, product, or even human being. The card, which can react through radio waves, contain all information for identification of the object or person it’s attached to. As to how fast it can be detected will depend on the power of the machine. Some are extremely sensitive that even if you’re meters away you can already be detected. Others will only function if you’re near the RF scanner.

There are also two components that make up the RF card. One of these is the integrated circuit, which has three functions: (1) modulates the radio signals from the RFID to the scanner and vice versa, (2) store and process information, and (3) other functions that could have been customized by the enterprise. You can also find an RFID that doesn’t have any chip attached to it, yet it still possesses some special parts that allow it to function like any circuit-based RFIDs. This one is a lot cheaper, and you can place it directly into any product.
