RFID Specific Terms
Transponder Transponders are devices that receive an excitation signal, and respond by transmitting back a
message.
Excitation Signal The excitation signal is a form of electromagnetic energy that is used to wake up the tag.
Response Signal . The response signal contains information that allows you to identify: the transponder (the object
to which it is attached), the reading point which excited the tag, battery status etc.
Reading Points Reading Points are installed at strategic areas on the site where you want to identify objects that are
passing within a specified range. .
Communication Links When using Transponders and Reading Points, two wireless communication links exist. They are:
Uplink - from the Reading Point to the Transponder, and Downlink - from the Transponder to the
Reading Point.
Postal RFID System
The International Postal Corporation (IPC) required international end-to-end mail performance
monitoring to implement new management and financial control systems. This monitoring and
controlling is supported by an international agreement known as REIMS (Remunerating Exchanges
of International Mails).
The Postal RFID System was developed in response to the IPC’s requirements.
The main objective of the Postal RFID System is:
• To monitor the movement of the probe letters at key points in the system
• To supply evidence of mailing system performance
• To highlight problem areas.
