Barcode presentation 2013
Mr. Woodland and Silver developed the barcode after being asked by a supermarket chain to find a better way to track inventory. Woodland drew lines of different thicknesses representing codes while visiting Miami in 1948, which led to the Universal Product Code barcode. A barcode uses a scanner to read patterns of bars and spaces that represent data about an object. It begins with a start character, ends with a stop character, and may include a checksum for error checking. Major barcode types include linear codes like UPC, Code 39, Code 128, and 2D codes like PDF417 and Data Matrix that can encode more data in less space.

Barcodes provide a machine-readable representation of data through parallel bars and spaces of varying widths. In 1948, Bernard Silver and Norman Joseph Woodland began developing barcode technology, filing the first patent in 1952. Initially used for inventory tracking, the first product scanned with a barcode was a pack of Wrigley's gum in 1974. Barcodes store data through varying widths that are read by scanners and decoded into text information. They enable rapid data collection and accurate tracking of products throughout the retail supply chain.
Barcode history and Future
Barcodes represent alphanumeric information as patterns of black and white bars of varying widths. They were first used industrially in the 1960s and began appearing on grocery products in the 1970s. Barcodes automate processes like data entry by allowing information to be scanned rather than manually typed. There are two main types: linear barcodes like the UPC code and 2D barcodes. Barcodes are now widely used across industries like retail, warehousing, and healthcare to identify and track items.

Barcode Technology ppt
Barcode or Barcode Reader is an optical machine-readable representation of data relating to
the object to which it is attached. Originally barcodes systematically represented data by varying
the widths and spacing of parallel lines, and may be referred to as linear or one-dimensional
(1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two
dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to
as barcodes as well. A barcode reader uses a photo sensor to convert the barcode into an
electrical signal as it moves across a barcode. Mechanism: The scanner then measures the
relative widths of the bars and spaces, translates the different patterns back into regular
characters, and sends them on to a computer or portable terminal. If we use barcodes, we get
online information without giving any data to the computer. If the manufacturing company
produces large quantity of products, then these barcodes are very useful.

Barcodes are optical machine-readable representations of data that were invented in 1948 and use a series of bars and spaces to represent alphanumeric information binary code that can be decoded by barcode readers. Their basic structure includes quiet zones, start/stop patterns, data characters, and optionally check characters. Barcodes use binary coding and decoding where bars represent 1s and spaces represent 0s. Key properties are magnification, bar height, substrate, and bar widths. Barcode technology involves software to generate unique codes, special thermal printers to print them on products, thermal paper that changes color with heat, and barcode readers to scan
Bar code-technology in tire industry
The document discusses bar code scanning and work-in-process (WIP) systems. It explains that bar codes contain predefined information that can be scanned automatically and accurately to collect real-time data. WIP systems track details about jobs like what is being worked on, its location, tasks completed, employees involved, and time/output metrics. The document provides examples of how bar code scanning and WIP systems can be implemented in manufacturing processes like tire production to track materials, production stages, and finished goods.

msr.pptx
The document summarizes a seminar on barcode technology. It defines a barcode as a format of dark bars and white spaces that enables automatic identification. Barcodes were initially used in industrial environments in the 1960s to identify items like rail cars. There are two main types of barcodes: linear barcodes and 2D barcodes. Barcodes are now widely used across various applications and industries to track items, provide accurate data input, and realize cost and labor savings compared to manual systems. The seminar also discusses barcode scanners and some advantages and disadvantages of barcode technology.
AUTOMATIC SMART SHOPPING TROLLY WITH BILLING
This document describes a proposed automatic smart shopping trolley system with billing capabilities. The system uses RFID tags and an ultrasonic sensor to identify and track items added to the trolley. When items with RFID tags are placed in the trolley, the tags are read by an RFID reader which updates the item and billing information. The trolley is also equipped with an ultrasonic sensor and WiFi connectivity to allow it to automatically follow and track customers in the store. The goal of the system is to provide an efficient solution to billing and reduce queues by performing billing directly in the trolley.
Q rcodes
The document discusses QR codes, which are 2D barcodes that can encode more information than traditional 1D barcodes. QR codes allow for quick reading and have error correction capabilities. The document explores using QR codes in educational settings by linking physical materials to online resources. It also provides information on creating and sharing QR codes using various free online QR code generator sites.
