Radio Frequency Identification Tags are a technology that have infiltrated many aspects of our daily lives. The RIFD tag is a small radio wave transmitter that can be embedded in almost anything. They have many uses.
Potentially, they have promise for making our lives easier. An example of this is using a Fast Pass on the Bay or Golden Gate Bridge. Your card transmits a signal to a rasio reciever and it counts you while debiting your account. This makes traffic flow more smoothly and decreases time waiting to pay a toll. Another good use is the prevention of shoplifting. RFID tags are placed in merchandise in a store and when you check out they are deactivated. Items not purchased do not get deactivated. When a person stealing leaves the store alarms are set off.
On the other hand there are potentially privacy invaing outcomes of RIFD technology. People are talking about having RIFD tags placed in Children in order to locate them if lost or abducted. While this could help many unfortunate situations, it also means that someone, somewhere, can locate you without you wanting them to. This is scary and invasive into personal privacy.
