1.      Introduction

The KEM6008 is a low cost high performance OEM proximity reader module for use with a simple external antenna. The module features medium read range and small dimensions. The KEM6008 has good read range at 5Volts, making it ideally suited to a wide variety of applications. The same basic unit can be configured to most of the common output formats, including Wiegand, Magstripe and Serial ASCII, making it easy to upgrade existing installations.

3.      Principle

The reader module generates a 125KHz inductive field that extends some way beyond the module. When a transponder is placed within the vicinity of the reader module, it draws power from this field. Providing the field is of sufficient strength, the internal microcircuits contained in the transponder begin to function. Data is transferred from the transponder by means of amplitude modulation in such a manner that the transponder varies the rate at which it draws power from the field

In a way that corresponds to internal identity code preprogrammed in its internal memory. These changes in field power can be detected by the reader and converted back into a copy of the original data.
