An iPhone App Helps the Blind Identify Currency

Not all technology advances are bad and this specific app the iphone has seems perfect. I remember the movie "Ray" with Jamie Foxx which was a movie about the singer Ray Charles. As you know Ray Charles is blind so when he receives his payment for a gig how does he know if he is being paid the correct amount? Ray simply does not know at all! In one scene Ray asked that his pay would be given to him in all one dollar bills so he could know exactly how much he was being paid. If Ray had this application back then he would not need to do that at all. This application tells you what type of bill is in front of you. What you do is turn on the camera put the bill in front of the phone and a voice will speak and tell you the type of bill it is. People with vision problems such as the blind can benefit from this application tremendously. I feel an invention like this is what we need in our society. Anything that can benefit people is good. I do not really like the unnecessary things people spend time making. If we spent more time creating things that would benefit people such as the blind the technology world would be more beneficial rather then pointless.
