Identify the following components of the system discussed in your textbook

The input device is the laser beam that sweeps across the bar code; the process involves reading the bar code and transferring it to the computer system.Output devices include: The handheld scanner serves as the output device as it has a screen that displays the price of the product; feedback: (in terms of hardware – the handheld scanner is connected to a computer system by a Universal Serial Bus (USB) cable.The handheld scanner has a lens and a laser light that scans the bar code.

Software, – the scanner has a software program (POS software which comes with the scanner) that integrates the scanner with the computer system.

Data and network taxonomies: the database is located on the computer system and the scanner fetches the information from the database and then displays the information on the small LCD screen attached onto it. Data is transferred to the computer system by using Bluetooth technology. Please list as much information as you could find on the scanner system, and discuss the supporting technologies. The light detection system is a s photodiode that conducts electricity when light energy falls on it and does not conduct any electricity when light energy does not fall on it.

There are lenses on the scanner that concentrate the laser beam. This is made up of either highly polished glass or plastic. The scanner also has holographic disks used to record laser images. the material used for this disk is a highly reflecting material. Then comes the encoder (a photodetector) that will transfer the image to the computer in the (electrical signals) digital form. It consists of a converter that converts the read code in the form of light energy to a digital form that can be decoded by the software program. The barcode reader is connected to the central computer system via a Bluetooth.

This is the IEEE 802. 15. 3 protocol. b. Please classify that kind of a system is this (TPS, DSS, EIS, MIS, etc. )? Why? In this situation, the barcode scanner is functioning as a Point of Sale System (POS). This is because the scanner aids in determining the value of the goods after the customer might have bought them and is ready to pay for them. c. Having the information electronically in the system may provide opportunities for additional managerial uses. Other possible managerial use that the information can be put to includes accounting.

It would be easy to manipulate the data in order to calculate the profit or loss of the supermarket. Also, it also helps in accountability because the supermarket is able to monitor all the sales it has made. Also, the supermarket would be able to harvest data about which goods consumers are purchasing and at what rate. This would afford the supermarket the opportunity of stocking these kind of goods and by so doing, increase the returns in terms of profit. Also, manufacturers are able to determine which goods consumers are purchasing more, and focus on producing these particular goods.

Also, it gives them room to improve on the ones that seem not to be moving. In marketing, the supermarket can focus on commodities that are in high demand and also improve on the sale of the ones that are not in such a high demand. In Human Resources, the supermarket can identify sales representatives that are selling more goods and reward them accordingly while reprimanding the ones that seen not to be selling much. The supermarket can then fire the redundant workers and reward the hardworking ones accordingly.

In transportation, it can aid them in planning which products to stock in which part of the shop. Also in security, it would eliminate tampering with prices of commodities as some dubious customers may want to engage in. in this way, customers cannot have any reason for paying less for the commodities they purchase. d. When did the scanner system come into existence? Where was this technology initiated? Research and provide a brief history of the scanner technology (during the past 20 years). The history of bar code technology is a long and convoluted one.

it is the story of one of the technologies that took a lot of research and time to complete because most of it was by personal effort on the part of the inventors. The invention is credited to Joseph Woodland and Bernard Silver in 1952. They were awarded the patent for the first barcode. it was initially designed as the structure of a bull eye model and the reader was an infrared sensitive inc. however the inventors found out that this was too expensive and they had to change it. They finally settled for code identification through the medium of identifying patterns. Bar code was first commercially in 1966.

By 1970, a company set the standard for writing the code. It was called the Universal Grocery Products Identification Code (UGPIC). This code evolved to become the (Universal Product Code) U. P. C symbol set in 1973. The UCC (formerly The Uniform Product Code Council, Inc. ) is responsible for issuing product numbers and specifications. e. Research and report on how such scanner type related systems will be operating in the future. What are the new technologies, such as RFID, in this area? State other types and names, and describe them. Barcode scanners are being taken a step further.

The new kinds of barcode scanners being developed nowadays now come with in-build cameras instead of normal laser scanners. They are called two dimensional (2D) scanners. They use a small video camera to capture the bar code image. The reader then decodes the digital image with a digital image processing device which is in built. Video cameras use the same CCD technology as in a CCD bar code reader except that instead of having a single row of sensors, a video camera has hundreds of rows of sensors arranged in a two dimensional array so that they can generate an image.

`This image is then processed, either by the scanner if it is a PDA scanner of the image is transferred to another kind of processing machine, it can ne a computer system f. Which countries and companies are at the forefront of the development of RFID technology? Is there any international standard emerging? What new societal issues or challenges are they likely to create? Samsung is one of the companies in the forefront of RFID technology research. It is in the process of deploying RFID systems into its wide array of mobile phones.

The company is an international company. Japan is also one of the countries that are intensively researching into the RFID technology. Various companies in Japan are also researching into the technology. Challenges might come in the area of implementing RFID technology because some people are already speculating on the privacy infringement that RFID technology might pose to consumers since most of the commodities they could be purchasing would have been labeled and this has the potential of reporting the location of the individual.

Therefore, unless people are reassured that this is not going to take place, they might not embrace the technology. A lot of factors could also militate against the implementation of FRID technology. They include the environment, cost, resistance to technological change, lack of integration and as mentioned earlier can all influence the implementation of this technology.
