The US Department of Homeland Security has decided that 1 million US passports will contain radio frequency ID chips in 2005, moving to a universal system from 2006. these RFID tags will allow customs officials to scan passports using special radio receivers. They will not have to approach the travellers directly but can scan them from nearby. The passports will contain biometric and other information.It will be faster and more convenient for customs but there are a number of dangers, including: the shielded cover are ineffective when a passport is open, and that a passport may have to be opened for inspection in a public place such as a hotel, a bank, or an Internet cafe. An open passport is subject to illicit reading of chip data, such as by a government agent who is tracking a passport holder's movements or by a criminal who is intending identity theft
