radio-frequency identification (RFID) chips that can be used to store data and transmit it via radio waves: Sounds like A SIM CARD once enough people are carrying the cards, officials other than border guards may wish to take advantage of the ability to track and identify people at a distance.

"Police will be really tempted to seek the authority to identify people in public spaces. The temptation will be irresistible to use the technology," whats in your wallet never belongs to you or does it but unlike bar codes, a line-of-sight between the tag and reader is not required.



One technology is designed for identity management that must come in close contact with the reader in order to be read. The other, designed for applications like tracking pallets of goods through a warehouse, can be read at a distance.

"The problem is that we're using the pallet technology [for driver's licences]," LEO can track you from a great distance and you're not going to know that they are keeping track of you. just human cargo whats your tracking #




The fact that the cards can be read by anyone with a CARD reader and not just border officials there is little people can do with the identification number that is the only information on the driver's licence chip.

Advanced Card Technologies Association of Canada disagreed, arguing that each identification number is linked to an individual who can be tracked using the number.

"I'll know that it's you," "and everywhere you go, when I find that PIN number, I can use that to further identify who you are, where you live, other things about you."However, the provinces issuing the cards said they are also preventing that kind of tracking by providing a special sleeve of metal mesh called a Faraday cage, which prevents the cards from being read at a distance.the sleeve used in used to protect enhanced driver's licences in the states of Washington and Vermont. Boston-based computer security firm RSA Laboratories, tested the sleeve used by Washington State and found that even while inside the sleeve, an enhanced driver's licence can be read from half a metre away.

United States will start requiring Canadian visitors to show their passports at land and sea border crossings to the U.S. unless they have an enhanced driver's licence. The RFID chip is supposed to make the licence harder to duplicate for use in identity fraud.What is RFID?

RFID is technology which works on radio frequency and it is used for the auto-identification for the different object.

The RFID system mainly consists of two parts.
1) RFID Reader or Interrogator
2) RFID Tags

In this RFID system, this RFID reader continuously sends radio waves of a particular frequency. If the object, on which this RFID tag is attached is within the range of this radio waves then it sends the feedback back to this RFID reader.
And based on this feedback, RFID reader identifies the object.

RFID tags:

Now, three different kinds of RFID tags are commercially available.
1) Passive tags
2) Active tags
3) Semi-passive tags

These passive tags do not have any power supply. They used to get their power from the incoming radio waves from the Readers.

While active tags have a power source for their internal circuitries. And for sending the response to the reader also, it uses its own power supply.

In the case of semi-passive tags, they have a power supply for internal circuitries, but for sending the response it relies on the radio waves received from the Reader.

Operating Frequency:

This RFID system is mainly operated in three frequency bands.
1) LF: Low-Frequency band
2) HF: High-Frequency band
3) UHF: Ultra High-Frequency band

The exact frequency of operation varies from country to country.

Operating Principles:

Most of the RFID systems operate on any of this two principles.
1) Load Modulation
2) Backscattered Modulations

Applications of RFID:
1. Institutions: Library, Hospitals, Schools, and Colleges
2. Transportation and Logistics
3. Access Control
4. Sports
5. Animal Tracking my thats cold
