Gone in 60 seconds–the high-tech version

“Unlike remote keyless entry systems, keyless ignition systems are passive, don’t require a battery, and have much shorter ranges (usually six feet or less); instead of sending a signal, the keyless ignition system relies on a signal emitted from the car itself. Keyless ignition systems allow you the convenience of starting your car with the touch of a button without removing the chip from your pocket or purse or backpack.”

What is RFID?

“RFID stands for Radio-Frequency IDentification. The acronym refers to small electronic devices that consist of a small chip and an antenna.”

“RFID devices will work within a few feet (up to 20 feet for high-frequency devices) of the scanner. For example, you could just put all of your groceries or purchases in a bag, and set the bag on the scanner. It would be able to query all of the RFID devices and total your purchase immediately.”

A Radio-Frequency IDentification system has three parts:

* A scanning antenna
* A transceiver with a decoder to interpret the data
* A transponder – the RFID tag – that has been programmed with information.

The scanning antenna puts out radio-frequency signals in a relatively short range. The RF radiation does two things:

* It provides a means of communicating with the transponder (the RFID tag) AND
* It provides the RFID tag with the energy to communicate (in the case of passive RFID tags).
