Passive RFID tags do not have an internal power source and must use a reader's energy waves to awaken and respond, relying entirely on the reader as a source of power.

Active RFID tags have their own internal battery and, with this power source, are capable of sending continuous pings or signals.

It includes two parts: an antenna for receiving and transmitting a signal, and an integrated semiconductor (microchip). ( 25) RFID Tagsįigure 8 presents the standard design of an RFID tag. While the RFID ID method may seem like simply an ID tag, it is a system that includes three basic components-the tag, the reader, and middleware. RADIO FREQUENCY IDENTIFICATION TAGS RFID Components Polypropylene, polyester, or vinyl tags can cost as little as a few cents each but would not stand up to harsh environments. These tags have a 30â€‘year life expectancy in harsh environments.

For example, for a 2-square-inch aluminum tag hardened for exterior conditions having a thickness of 12/1000 of an inch with adhesive, the price is $0.42 each for an order of 10,000 units, while changing the thickness to 20/1000 of an inch raises the unit price to $1.40. Price is greatly impacted by the quantity, material, and size of tags ordered, along with the attachment mechanism. ( 12) This cost excludes training, support, server software, and personal digital assistance (PDA) software.

Therefore, barcode software acquisition costs range from $2,500 to $35,000 despite barcode labels themselves being inexpensive. Formal systems with proprietary software can be costly.

Information can be scanned directly into readily available office spreadsheet programs or can require complex software to code specific elements into agency databases. Tags that can withstand harsh environmental conditions may cost considerably more. Users can print barcodes on any printable medium and use a cell phone or tablet to scan barcodes. The distance that a scanner can read a barcode is directly dependent on tag size and scanner type. Reading distance varies, but generally scanners can read 1D barcodes at twice the distance of 2D barcodes. Scanners also take longer to read a 2D barcode than a 1D barcode. Read rates for barcodes are limited to one barcode per scan. Scanners can read 2D barcodes at some angles. Line of sight is required for both 1D and 2D barcodes. The performance of barcode tags depends greatly on many factors, including: Barcode standards are provided by the GS1 system established by the Uniform Product Code Council, which has been in place since 2005.įigure 7.

In considering barcodes and serial numbers, the construction of the tag is very similar, and often manufacturers print both barcodes and corresponding serial numbers along with any additional information a buyer might want on the tag ( see figure 5). Similarly, serial numbers are a group of alphanumeric characters that users print on a tag and attach to the product or asset they want to identify and document. HOW THIS REPORT IS ORGANIZEDīarcode tag identifiers consist of printed lines, spaces, and shapes on a tag that users attach to the product or asset they want to track.

It is assumed that transportation agencies would deploy both barcode and serial number technologies post-manufacture by creating and attaching a tag using the same printing and installation process. Therefore, they are treated as the same method in this chapter. There was no clear separation in the literature or practice between uses of barcodes and serial numbers as tag identifiers (often barcodes have both the printed matrix and serial number).

RFID devices, either active or passive.

This review focuses on the following three primary tag identifiers as ID methods: This chapter provides an overview of the specific tag identifier technologies, and their relative performance, used by transportation agencies to tag roadside safety hardware.
