RFID and distance measurement

Hello Guys,

I have a new project that I want use RFID to verify ID of item and I need measurement distance from reader to TAG. The maximum distance between the reader to TAG is about 7 cm and I want know distance between reader to TAG with accuracy about 1 cm.

Is it possible?

Definition of: RFID

RFID

(Radio Frequency IDentification) A data collection technology that uses electronic tags for storing data. The tag, also known as an "electronic label," "transponder" or "code plate," is made up of an RFID chip attached to an antenna. Transmitting in the kilohertz, megahertz and gigahertz ranges, tags may be battery-powered or derive their power from the RF waves coming...

What is RFID?

Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and...

Passive RFID Tags

Passive tags are comprised of three elements: an integrated circuit or chip, an antenna, and a substrate.

The RFID chip stores data and performs specific tasks. Depending on its design, the chip may be read-only (RO), write-once, read-many (WORM), or read-write (RW). Typically, RFID chips carry 96 bits of memory but can range from 2-1000 bits.

Attached to the chip is the...

Transmit Power

RFID readers and active RFID tags actively transmit RF energy to carry information from one to the other.

Active tags have a battery, or an external power supply, so have enough power available to allow them to transmit up to the maximum legal power limit.

A passive tag doesn't have a battery. So where does it get the energy to power...
