Radio frequency identification or RFID is a type of automatic identification system used to organize and track people, goods and other assets. It is a portable tag contains data that includes identification or location of the product it is attached to, or specific characteristics about product tagged such as price, color or date of purchase) that are stuck on any kind of product (cloths, smartcards, currency) that contains a tiny chip, which can transmit data wireless to readers and exchange information with a reader (which are often connected to computer network) via radio waves. The reader can pass information to a database and software application that processes the data according to the needs of a particular use. So, it could be say that the RFID technology is key lever for that increased productivity.RFID use that involves personal information can spark privacy concerns. RFID tags come in different sizes and shapes. Some tags are easy to spot, such as the hard plastic tags connected to merchandise in stores, while other tags are no bigger than a small section of pencil lead. On the other hand, some tags are designed to be embedded within the fibers of a national currency.
There are some kinds of concern about the RFID privacy. For example, the newest technology embedded in some RFID readers allow them to read data transmitted by many different RFID tag. We should be aware and careful about the potential abuses of such technologies, so we will not fail to incorporate them on the right time. By acknowledging the weak areas in the system on early time and by working to eradicate those vulnerable security points, the current RFID technology will continue to improve and perhaps be a reasonably secure option for widespread.
