Week 3- Input and Output

Okay, I am going to recap on what I have done with my electronic credit cards. First I touched on the biggest problem this project will have – privacy. How will people not get your credit card information off of your phone? How do I know the connection on my phone is protected? Well, each account is linked directly to your bank account that you have online, the only additional feature will be the barcode, very similar to the starbuck’s app that you hand to the cashier and they scan.

            In week two, I touched on how credit card companies and banks will create Excel spread sheets that will run automatic program checks to notify workers of what ever category they call for. This will insure that they have maximum organization and that each person is not overlooked.

Overall, I feel like the basics are laid down for a very successful application.

This week I am going to look at the input and output of the program. I know many questions are rising of the true safety and reliability of a credit card on your phone. Google just released their new application called Google Wallet( http://www.google.com/wallet/). This application allows users to ditch the big bulky wallets and electronically scan everything (where it’s accepted) and go worry free about ever forgetting something important again.

            The new and most innovative technology out there is called Radio Frequency Identification (RFID). This software allows users to simply scan and go without having to wait for a conformation that it was scanned. It has been most commonly used for EZ-Pass. The RFID chip would be imprinted into the backs of each new cell phone coming out into the market. The user would then use the online banking system of their choice to link there credit cards to their phones.

            How is this going to be protected? 

First each RFID chip will be pass word protected, before a person can scan the item from any distance they will need to input a personalized password allowing the software to send out frequency waves that will be received by a reader which will then instantly send the information to a computer system at the user’s respective bank or credit card company.

            The cheapest and most effective way to embed these tags into cell phones is going to use passive tags. This will require the user to be close enough to the readers that other systems or person’s attempting to hack your information will not have access to it.

            The tag will not be any more noticeable than the back of a regular cell phone case will a small symbol to identify that it is RFID enabled.

            What about the metal interactions?

            Each case will be protected by anti-static guard material. This means that the case will be coated in a hard, smooth plastic that will protect the chip from metal to metal connection, therefore insuring that the chip will not shock out.

            If you have any questions thus far, please feel free to comment on this article.

Stay tuned next week for Storage Capacities!
