Item No:PML125K

Item Name:Module-RFID
Feature
A reader with PML125K serves both as a magnetic field generator and a decoder to energize a tag and receive transmitted data from it. In other words, an AC power is generated across the coil whenever the magnetic filed pass through the antenna coil of tag. Then, the voltage will power up the tag to transmit its stored information back to the reader. It is so called backscattering. Signal transmission rate is around 1K bit to 4K bit per second. It is a form of modulated Signal. A reader through its coil antenna can receive these signals. Demodulation process followed, these signals are transformed to digital data strings for further decoding. By using PML125K, A variety of chip brands are supported; such as, EM, Microchip, Philips, Temic, and so forth. It will be your simple solution with low cost and less effort to implement your complex RF system.

Purpose


WFE-125K-xx series provide either single direction or bidirection communication through

contactless radio frequency (RF) wave. Amplitude Shift Keying (ASK) mode is employed
as a modulation method to carrier signal in a radio frequency of 125K Hz. It is used to
accomplish actual modulation of signal transmission from a tag to a reader in a speed
fallen in 1K bit to 4K bit per second.

Applications


Mobile / PDA application

RFID integrated mobile phone or PDA is shown in
market now. And most of mobile phone key
manufacturers are R&D mobile phone with frequency
13.56 and UHF Gen2. The idea is to integrated RFID
module into mobile phone/sensor to enable 
consumers to read proximity label.
   
Intelligent Shelf

The great part of Intelligent Shelf is to raise the
revenue which can make sure no shortage on shelf
and no need clerk to check anymore. When combine
selling mechanism in the future, supporting system
can record selling data, and have cross checking
among leaving/selling of products displayed on shelf.
For example, how many times “product A” leave the
shelf? How many “product A” were sold? How many
clients take “product A” and purchase it after taking it
from shelf? All those information are helpful for
companies to analyze selling condition of their
products which could apply to chain stores and saving
the cost of human resources.
   
Treadmill

Add module into the treadmill to enable to read
member’s personal information, preferable speed,
time, etc. among exercising which will make the
treadmill more humanized.
