RFID Basics

What is RFID?
RFID stands for radio frequency identification. It is an automatic identification technology whereby digital data encoded in an RFID tag or “smart label” is captured by a reader using radio waves. Put simply, RFID is similar to bar code technology but uses radio waves to encode and capture data to and from tags, rather than optically scanning the bar codes on a label. RFID does not require tag or label to be seen to read its stored data—that's one of the key characteristics of an RFID system. However it is typical to find bar code and RFID used together.
What are the key attributes of RFID?
Passive smart label RFID systems offer unique capabilities as an automatic data capture system in that they:
Provide error-free, wireless data transmission that is battery-free and maintenance-free.
Do not require line-of-site scanners for operation.
Allow stored data to be altered during sorting or to capture workflow process information.
Work effectively even in harsh environments with excessive dirt, dust, moisture, and temperature extremes.
What is an RFID tag?
RFID tags consist of an integrated circuit (IC) attached to an antenna—typically a small coil of wires—plus some protective packaging (like a plastic card) as determined by the application requirements. RFID tags can come in many forms and sizes. Some can be as small as a grain of rice. Data is stored in the IC and transmitted through the antenna to a reader. RFID tags are either “passive” (no battery) or “active” (self-powered by a battery). Tags also can be read-only (stored data can be read but not changed), read/write (stored data can be altered or re-written), or a combination, in which some data is permanently stored while other memory is left accessible for later encoding and updates.
What is a “smart label”?
“Smart labels” are a particularly innovative form of RFID tag and operate in much the same way. However, smart labels consist of adhesive labels with an embedded ultra-thin RFID tag “inlay” (the tag IC (integrated circuit) plus antenna). Smart labels combine the read range and unattended processing capability of RFID with the convenience and flexibility of on-demand label printing. Smart labels also can be pre-printed and pre coded for use. In on-demand applications, the tag inlay can be encoded with fixed or variable data and tested before the label is printed, while the label can contain all the bar codes, text, and graphics used in established applications. Smart labels are called “smart” because of the flexible capabilities provided by the silicon chip embedded in the tag inlay. A read/write smart label also can be programmed and reprogrammed in use, following initial coding during the label production process.
What is an RFID reader?
A reader is basically a radio frequency (RF) transmitter and receiver, controlled by a microprocessor or digital signal processor. The reader, using an attached antenna, captures data from tags then passes the data to a computer for processing. As with tags, readers come in a wide range of sizes and offer different features. Readers can be affixed in a stationary position (for example, beside a conveyor belt in a factory or dock doors in a warehouse), portable (integrated into a mobile computer that also might be used for scanning bar codes), or even embedded in electronic equipment such as print-on-demand label printers.
How does RFID work?
Information is sent to and read from RFID tags by a reader using radio waves. In passive systems, which are the most common, an RFID reader transmits an energy field that “wakes up” the tag and provides the power for the tag to operate. In active systems, a battery in the tag is used to boost the effective operating range of the tag and to offer additional features over passive tags, such as temperature sensing. Data collected from tags is then passed through familiar communication interfaces (cable or wireless) to host computer systems in the same manner that data scanned from bar code labels is captured and passed to computer systems for interpretation, storage, and action.
