Radio Frequency Identification (RFID) is a practical and useful technology for locating items without the requisite close proximity as needed with older technology, such as bar codes. However, new technologies such as RFID "powder," internal and external pre-crime detectors, and insertion into children's clothing and other personal items have pros and cons associated with the practicality of its use. In addition, RFID use in access control, identification documents, and banking cards, while convenient and illegal to jam, may lack important security features to prevent unauthorized scanning and usage of the data contained. The REAL ID Act mandates using RFID in ID cards that most Americans should carry for domestic airline travel and must carry for international travel. This discussion will examine current RFID technology and security concerns as well as how the RFID technology implemented in REAL ID Act cards and passports may pose privacy and security risks.
