Big Darn Deals ch. 6

The first is that I did not know about RFID's and that Wal-mart and other stores were putting RFID tags on different items. Wouldn't it be cool if we didn't have to stand in those long lines at the grovery store? Supposedly RFID tags could take care of that! The second is that I had no idea that there were so many different types of storages. They all have their advantages but also have their disadvantages. The ones talked about on the slide are all older ways of storage but are still used today! I guess they all have their own purpose. The third, I was looking at all the different memory cards in the book! There are so many different sizes and types that I had no clue about! There are so many devices that need memory cards. I always thought that cameras were the only thing, but no way!
