Radio Frequency ID

Radio Frequency Identification (RFID) could potentially be used in virtually all industries, commerce, and services where data acquisition is of great importance. RFID technology enables us to remotely acquire data using radio frequency.

We have developed a prototype of RFID system based on EPCglobal Standards. For the prototype development, we are using Texas Instruments' RFID evaluation kit (Micro Reader S 2000). Currently we are in the design phase of RFID Savant Server.

About RFID

Radio Frequency Identification (RFID) is a technology which enables us to remotely acquire, store, and retrieve data using radio frequency. In its simplest form it consists of a reader, transponder, and a computer. Both the reader and transponder have antenna which transmits radio signals. When the transponder comes in the electric/magnetic field of the reader antenna, it responds to the commands sent from the reader. The response is either sending the data stored in the transponder's memory or writing in its memory the data sent by the reader. The reader is connected to a computer which manipulates and processes the data exchanged between the reader and the transponder.

Potential Application of RFID

Potential applications for RFID may be identified in virtually every sector of industry, commerce and services where data is to be collected. The attributes of RFID are complimentary to other data capture technologies and thus able to satisfy particular application requirements that cannot be adequately accommodate by alternative technologies. Principal areas of application for RFID that can be currently identified include:

  • Transportation and logistics
  • Manufacturing and Processing
  • Security

A range of miscellaneous applications may also be distinguished, some of which are steadily growing in terms of application numbers. They include:

  • Animal tagging
  • Waste management
  • Time and attendance
  • Postal tracking
  • Airline baggage reconciliation
  • Road toll management

As standards emerge, technology develops still further, and costs reduce considerable growth in terms of application numbers and new areas of application may be expected.

Some of the more prominent specific applications include

  • Electronic article surveillance - clothing retail outlets being typical.
  • Protection of valuable equipment against theft, unauthorized removal or asset management.
  • Controlled access to vehicles, parking areas and fuel facilities - depot facilities being typical.
  • Automated toll collection for roads and bridges - since the 1980s, electronic Road-Pricing (ERP) systems have been used in Hong Kong.
  • Controlled access of personnel to secure or hazardous locations.
  • Time and attendance - to replace conventional "slot card" time keeping systems.
  • Animal husbandry - for identification in support of individualized feeding programmers.
  • Automatic identification of tools in numerically controlled machines - to facilitate condition monitoring of tools, for use in managing tool usage and minimizing waste due to excessive machine tool wear.
  • Identification of product variants and process control in flexible manufacture systems.
  • Sport time recording
  • Electronic monitoring of offenders at home
  • Vehicle anti-theft systems and car immobilizer

A number of factors influence the suitability of RFID for given applications. The application needs must be carefully determined and examined with respect to the attributes that RFID and other data collection technologies can offer. Where RFID is identified as a contender further considerations have to be made in respect of application environment, from an electromagnetic standpoint, standards, and legislation concerning use of frequencies and power levels.
