"Privacy campaigners are aghast over claims sourced from a leaked government letter that suggest biometric ID cards will be fitted with radio transmitting technology to track people's movements. The letter, reportedly obtained by a national newspaper, stated that the incoming cards need special chips to comply with internal ID card rules, such as being able to locate airport scanners. Although the Home Office confirmed the necessity of the radio chips, it pointed out certain data would only be transmitted over a very short distance, up to 2cm. But ID card and surveillance critics warned that the chips, expected to store a person's name, age, date of birth and biometrics, could be abused by both government and hi-tech criminals for their own purposes."
