Barcodes and QR codes can store various amounts of data. Barcodes can hold up to 20 characters of information and are one-dimensional, while QR codes are two-dimensional and can store up to 4,000 characters. Scanners and smartphone cameras have advanced to read these codes more accurately. Software decodes the coded information, compensating for distortions to determine the actual data being represented for uses like product information, sending users to URLs, and providing information to vendors in advertisements.

Bar codes and its type with different scanner and its application
The document provides an overview of barcodes, including their history, technology, terminology, types, uses and benefits. It discusses that the first barcode patent was issued in 1952 and how they started being used widely in grocery stores in the 1970s to automate checkout processes. Barcodes represent a unique product identity and allow for accurate, real-time data collection that saves labor costs and improves resource management. Common barcode types include UPC, Code 128 and Data Matrix, which are used across various industries like retail, shipping, warehousing and healthcare for applications like inventory tracking, electronic data interchange and patient identification.
BARCODE TECHNOLOGY.pptx
This document provides an overview of barcode technology. It defines a barcode as a machine-readable visual representation of data that varies the widths and spacings of parallel lines. Barcodes store product information like manufacturing date and price. They work by being scanned by barcode readers that convert the patterns into binary code for computers. Barcodes are widely used for inventory management in stores and healthcare settings to identify patients and documents. They provide benefits like fast and accurate data collection but require special scanning devices and are susceptible to damage.
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.
Qr codes and libraries
QR codes allow for more information storage than traditional barcodes. They are increasingly being used by libraries to provide digital links and additional content related to physical materials through scanning a QR code. Examples of library QR code uses include providing links to online resources, events calendars, instructional videos, and digital versions of materials. QR codes can be created using free online generators and considering the code size, clarity, and context of its display is important for usability.
Qr code
QR codes are matrix barcodes that can be read by smartphone cameras and contain information like text, URLs, or other data. Users scan the code with their phone which then directs them to the encoded information. QR codes are categorized based on whether they use open standards like QR codes that anyone can use, proprietary codes only readable by certain apps, readers that allow phones to scan codes, or companies that create real-world solutions using barcodes. QR codes have various uses like providing additional information in magazines, linking to movie trailers, digital contact cards, and more. They can be created using free online generators or apps to encode a URL or information for others to access.

Editor's Notes
- The data gives of a numerical code when scanned. This code can represent a multitude of things, in most cases we see bar codes on products. When the code is scanned the database references the code number to the item and gives back the price. How much data a code can hold is represented by characters. Bar codes max out at 20 characters. Problem is with only 20 characters with more sophisticated products are not able to be represented.
- 40 characters.
- Scanners sends out laser and the lines reflect the light. The different lines reflect the light differently. Almost all scanners have a decoding circuitry, which changes the light picked up to the number which represents the product. With that number a system/ processor can spit out all the information about that product.
- 2 dimension- the code gives of information in two directions. Therefore holds more information, up to 4,000 characters much more than the 20 characters of the original bar codes. The squares seen on the QR code are to help determine where and the size of the qr code.
- Smart phones now have capability to scan qr codes with apps through the use of the phones camera.
- A QR code can represent a product just as bar codes do, but they can also send you to web pages. When a smartphone with access to the internet scans the code it will open up their web browser and send them directly to the URL imbedded in the code. If you were to scan this adds qr code it would take you to polo’s website. The Vender such as polo here, knows where the code was scanned in the US, if the person bought something after scanning the code, and much more. This information helps the venders locate their top retail area’s and more. QR codes have not just made getting a product of the shelf easier but has opened up a whole new world of advertisement.
