Radio Frequency Identification (RFID) Technologies

About RFID Technologies

RFID is short for radio frequency identification. With RFID, the RF tag, or transponder is used to transmit signals which are read by a separate processing device (reader) that converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can analyze the data.

RFID consist of two different types. Passive tags use the radio frequency from the reader to transmit their signal. Passive tags will generally have their data permanently burned into the tag when it is made, although some can be rewritten. Active tags are much more sophisticated and have on-board battery for power to transmit their data signal over a greater distance and power random access memory (RAM) giving them the ability to store up to 32,000 bytes of data.

CSI RFID Product Development

RFID is a frontrunner technology for automatic identification and data collection. To date, CSI has participated in a number of development and test scenarios involving RFID. However, due to the current lack of RFID standards and disproportionate cost for supply chain partners to adopt RFID, for CSI, RFID product technology remains in a development mode.
