Week #4: Input and Output

This week in class we talked about input and output. One of the most interesting things discussed, in my opinion, was the RFID chip. I think this would be the perfect technology to use for my tracking product! If it can be used to track a lost kid, it can certainly track a cellphone. :)

A perk of using RFID would be that it's inexpensive. In some case, it can cost as little as 5 cents per chip. Though I doubt my product would be that cheap, a starting price being that inexpensive could mean that my product wouldn't be all that costly, either, meaning that it would be affordable to a wider variety of people.

A disadvantage to using RFID is that it's still a developing technology and it's not 100% secure yet. As a result, the public domain doesn't have the best perception of it. However, as fast as technology is going these days, and how useful RFID could be, I'm sure the technology for it will have improved quite a bit within the next year or two, so after long, there won't be anything to worry about.
