RFID Reader, the vital component of RFID system

RFID is used to automate the process of capturing batch production information for lot tracking. This eliminates the manual scanning typically required with a bar code solution through the use of container and location-based RFID tags interacting with readers on material-handling equipment.

RFID Reader(interrogator) is a vital RFID system component. A transmitter/receiver that reads the contents of RFID tags in the vicinity. Also called an "RFID interrogator." The maximum distance between the reader's antenna and the tag vary, depending on application.

An RFID reader typically contains a module (transmitter and receiver), a control unit and a coupling element (antenna).RFID Reader transmits and receives radio waves. Reader not only interrogates tags for information, but it can also be used to program (write) information to tags. The RFID reader uses an antenna to send and receive signals to and from RFID tags. The antenna can be either an internal or an external addition.

In addition, readers can be fitted with an additional interface that converts the radio waves returned from the RFID tag into a form that can then be passed on to another system, like a computer or any programmable logic controller.
