Blackhawk Under the Radar

摘要

How secure are your identity and location? Perhaps far less secure than you think. Even when turned off, electronic devices emit a slight electronic signal that can be identified by thieves or others using detection devices. Passports, passport cards, many driver's licenses, identity cards, and credit/debit cards contain radio-frequency identification (RFID) chips with sensitive personal information. RFID is the wireless non-contact use of radio-frequency electro-magnetic fields to transfer data. Although the RFID chips contained in passports are supposed to be readable only at a few centimeters, in one test they could be read at a distance of ten meters using specialized equipment.
