The idea of equipping shoes, hats, and persons with these little tags known as RFID tags (Radio Frequency Identification) is only one of recent discussion. These tags would be used for commercial use and could be able to tell all the information of a potential customer the second they walked in the door of their store. These tags lead the way to a whole new level of understanding the customer and meeting needs.
The way that this will impact society is how many people will think it is a violating privacy of people or how it is displaying unwanted information to unwanted users. Although it is just the stores and commercial retailers, the idea could spread like a disease and catch on everywhere.
The idea of tagging is much like cellular technology right now. With cell phones, you can get minimal information if needed, but with tagging, you would be able to see what size, favorite colors, name and address, etc. Many consumers may find that this is a breach of privacy allowing retailers to find out information about them that they wouldn't otherwise share.
Since tagging is such a new idea, it is impossible to really know the effects it will have on society. People may see tagging as a way to for the government or commercial retailers to control the consumers. This could lead to new levels of government control, organization, testing, etc. The world may not be ready for this kind of technology either. The only tagging that has been done up to this point is that of tagging animals and following their movements and how they live. For retailers to make the jump from wild animals, to civilized human beings may shock or even worse, offend many people.

Many companies to this day have experimented with tagging. A company out of Toronto is using tagging devices to tag luggage for passengers on airplanes. Other government agencies are using tracking devices to track the movement of illegal drugs.
Commercial retailers such as Hollister or Abercrombie and Fitch, however, have not used tagging to gain information about a customer as they walk in the door yet. That idea has not yet been introduced to our society. This having your information displayed for others to see as you walk into a store may concern American citizens. Since identity theft is such a popular crime in America, too many people may not approve of having someone other than himself or herself to see their personal information.
The way that this could be avoided though, is to make it optional. For a small fee you could have a chip placed in an article of clothing that you would wear frequently while shopping in the store. Not everyone would have this chip put in clothing. It could either be put in your shoe, hat, or other random article, but it will still be able to be identified the second you walk through the store door.
As a whole, RFID tags in clothing should be generally accepted by most of society. The impact this will have on society will most likely be a laid back sort of view of the product. Since it is not mandatory for every person to have one of these tags, most citizens shouldn't care if others are using these tags or not.
