Outline the purpose of the system. State and justify whether the TPS is a batch or real time processing system.
The purpose of an ATM (or the Automated teller machine)’s purpose is that of allowing the user to partake in financial transactions. This Transaction Processing system is a real time processing system. As the ATM needs to respond to the requests of the user such as verifying PIN numbers, account balances and other information.
Identify the participants, users, data information, and information technology for the two systems.
The participants would include the customers, the technicians.
The users would be the intended audience of the customers who would visit the machines as they make financial transactions such as withdrawing money or checking their balance.
The data would be the data stored on the smart cards/credit cards.

Explain how the systems function (include hardware and software).
The hardware of the system includes the
- Central Processing Unit (CPU)
- The Smart card reader
- A ‘PIN pad’ or PIN entry device
- One or more Secure cryptoprocessors
- The monitor – for displaying purposes
- The function keys – These are the keys used as to cause an operating system command
The majority of ATM systems use a Microsoft Windows operating system, primarily Windows XP Professional.

Determine the positive and negative aspects of the use of this system.
- The sheer convenience of the ATM systems. According to the Australian Payments Clearing Association, in June 2000 there were 11,819 ATMs in Australia, by June 2010 there were 28,764. This means that within a decade the amount of ATMS more than doubled. This results in the fact that there is almost always an ATM by a nearby location.
- Another positive access is the ease of access. There are usually but 16 keys on the system’s Pin Pad (10 of them being number keys) and 4 function keys.

Unfortunately, If the hardware is damaged, the user must wait until the system is manually fixed by professional technicians.
The system's backup procedures.
Thanks to technological advances in modern technology, Automated teller machines are now able to connect to other content servers and video banking systems, resulting in a lack of lost data, information and other content. Automated teller machines use the Grandfather-Father-Son backup.
In the event that a user attempts to threaten the physical integrity of the machine via violence in the attempt to steal money from the system - An ‘intelligent banknote neutralisation system’ is found on most ATMs world-wide (IBNS). –This system causes the money within the system to be damaged to the point of the object becoming redundant. The notes are marked as stolen and as such cannot be reintroduced into monetary circulation easily. The most common form of this is simple ‘cash degradation’ via ink

ATM Transaction Processing System


By Joshua Loader

How the use of this TPS has changed the nature of work.
Until ATMs were introduced into the circulation of society in the late 1960’s, people had to physically enter banks and make their financial transactions within certain limited times. ATMs changed this forever as now people can make their financial transactions 24 hours a day, 7 days a week at a large number of locations.
Social and ethical issues generated by the system.
- Data security - data security, data accuracy, data integrity
- The potential effect on participants, such as the automation of jobs once performed by clerks – perhaps resulting in job redundancy.

Hypothesis regarding the future directions of the system, considering current and emerging technologies
I believe that the future direction of this system will result in the ability of being able to pay bills (such as the weekly rent, for example) directly from the machine rather than physically entering a bank making payments.
The participants, users, data / information, and information technology for the two systems.
The participants be the technicians and the store staff, whilest the users would just be the store staff. The data would be the data stored on the server and the barcodes.



Software: The software the system uses a mixture of various key components, such as object identification, asset tracking, and service and order management.
Hardware: The hardware includes a Barcode reader that uses barcodes and radio-frequency identification (or RFID) tags to read data.

Inventory Control
The purpose of the Inventory control system is that of certifying the managing and location of certain materials or objects.

It is a Batch processing system.
The systems function (including hardware and software).
The system's backup procedures.
The system uses the round robin backup procedure,
How the use of this TPS has changed the nature of work.
This Transaction Processing System has changed the nature way modern shopfronts and libraries collect data regarding stock, assets, library books and merchandise. Before the system was popularised and subsequently used to automate supermarket checkout systems, simple non-electronic (and non efficient) systems were used such as punch cards.
Social and ethical issues generated by the system.
The future directions of the system, considering current and emerging technologies.
Every year there are many large advances in technology, it is very likely that whilst the basic ideas of the system will remain the same, minor short-cuts and workarounds will be made in order to gain a quicker, and a more efficient and effective result.
Why did you choose this multimedia format
Prezis are as creative as possible, they use an effective GUI as well as consistent in layout and is easy to use/read/understand.

What media types did you use in your presentation? Justify their use.

I used text, to present the informaton. Aswell as using animations to provide an easy to see follow presentation. The images are used to aid in giving a visual representation to go along with the text.
Social and Ethical issues related to the use of this Multimedia Presentation.
The social and ethical issues were virtually non-existent as the cost of creating a 'Prezi' presentation is free, and all the materials needed to research and create the presentation were previously aquired.

The social issues that arose regarding providing the appropriate sources when gaining information were also properly sourced.
The possible chances of a mistake in processing have been addressed and as such there is very little chance of affecting the data integrity of the system.
