What is RFID?

Radio Frequency IDentification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects.

How does an RFID system work?
An RFID system consists of a tag, which is made up of a microchip with an antenna, and an interrogator or reader with an antenna. The reader sends out electromagnetic waves. The tag antenna is tuned to receive these waves. A passive RFID tag draws power from field created by the reader and uses it to power the microchip’s circuits. The chip then modulates the waves that the tag sends back to the reader and the reader converts the new waves into digital data.

What is the difference between low, high, and ultra-high frequencies?
Just as your radio tunes in to different frequency to hear different channels, RFID tags and readers have to be tuned to the same frequency to communicate. RFID systems use many different frequencies, but generally the most common are low- (around 125 KHz), high- (13.56 MHz) and ultra-high frequency, or UHF (860-960 MHz). Microwave (2.45 GHz) is also used in some applications. Radio waves behave differently at different frequency, so you have to choose the right frequency for the right application.

Early Adopter In UHF/RFID
The  Singapore government here, through its agencies including A’STAR, IDA, EDB and SPRING have launched various scheme over the years to promote the RFID development, trials and adoption in Singapore. On February 2005, Kim Hiap Lee Co. (Pte) Ltd, the wooden ECR pallet leasing, a subsidiary company of LHT Holdings Limited of Singapore, as a early UHF/RFID adopter began it pilot.

RFID Implementation On ECR Pallet
Implementing RFID strategy is a complex process. The technology affects all parts of the organisation including process, enterprise systems, IT infrastructures and hardware. RFID expertise and planning is required in all areas for a successful RFID implementation.

The Pioneer RFID Pallet In Asia
After numerous Research & Development (R&D) and “trials & errors”, on January 24, 2006, witness by IDA, Kim Hiap Lee Co. (Pte) Ltd had successfully achieved 100 percent read rate for the ECR/RFID pallets passing through its RFID gantry during its pilot trial.
