Radio Frequency Identification is a generic term for technology that uses radio waves to identify living things or objects. There are many forms of identification but the most common one is radio waves to read and capture information on a tag attached to an object. A tag can be read from up to several feet away and does not need to be within direct line of sight of the reader to be tracked. RFID systems consist of three components. A RFID tag, an RFID reader and antenna. Antennas are used to transmit data to the RFID reader. The reader converts the radio waves to a more usable form of data. Then information collected from the tags is transferred to computer system where data can be stored and analyzed.
Our credit cards have ’’RFID tag’’. Contactless pos machines or card copying devices can easily access all the information in a tag and withdrawal or copy of card information can be done.
In our daily lives, it is very possible for us to encounter this kind of theft. That’s why we produce card protector wallets.
