• A bar code scanner scan the items and allows it to be viewd on the clerks screen, then its then allowed to be printed as a receipt, which helps both the clerk and the buyer to have a secure reliable transaction.
• A credit card machine, which allows transaction to occur directly without the use of cash, which makes safe and secure transaction possible.
• 1- a touch pad: This is an excellent alternative because it allows the user to intract with the computer directly, and it senses the heat source from the users hands. 2-This responds to the persons heat source on the monitor.

Criterion G

For my project, i want to help Al-Arqam school students to appreciate art, in a new way. Instead of looking at Art as a class to draw or pain, they can look at it as a competitive course in which they strive to have their artwork presented to the whole school.
I find the subject of Art extremely appealing, and i see that it is slowly disappearing because of the lack of enthusiasm and competitiveness. I have decided to create a magazine, or brochure in which the top ten art work are shown, with a summary of what that art work means and what type of mood it creates when others view it. This will definetley have many students enthusiastic about creating something magnificent enough to be printed, and distributed.
For many students Art isn't hard, but its boring, and there is no fun to it. With this project, students will change the view of many who have given up on competing in class, or draw and paint to pass, not for pleasure. When they see how fantastic art is they will change and will thus create an easier setting for many art teachers to come to work with.
