Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

The tags contain electronically stored information.

Passive tags collect energy from a nearby RFID reader's interrogating radio waves.

Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader.

Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object.

RFID is one method for Automatic Identification and Data Capture (AIDC).

A supply chain is a system of organizations, people, activities, information, and resources involved in.

A barcode is an optical, machine-readable, representation of data; the data usually describes something about the object that carries the barcode.

Originally barcodes systematically represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D).

Later two-dimensional (2D) codes were developed, using rectangles, dots, hexagons and other geometric patterns in two dimensions, usually called barcodes although they do not use bars as such.

Barcodes originally were scanned by special optical scanners called barcode readers.

Later applications software became available for devices that could read images, such as smartphones with cameras.

Productivity describes various measures of the efficiency of production.

A productivity measure is expressed as the ratio of output to inputs used in a production process, i.e. output per unit of input.

Productivity is a crucial factor in production performance of firms and nations.

Increasing national productivity can raise living standards because more real income improves people's ability to purchase goods and services, enjoy leisure, improve housing and education and contribute to social and environmental programs.

Productivity growth also helps businesses to be more profitable.

There are many different definitions of productivity and the choice among them depends on the purpose of the productivity measurement and/or data availability.
