Radio Frequency Identification (RFID) Technologies
About RFID Technologies
RFID is short for radio frequency identification. With RFID, the RF tag, or transponder transmits signals which are read by a separate processing device (reader) that converts the radio waves from the RFID tag into digital information. The digitized information can then be relayed to computers that can anlyze the data.
There are two types of RFID technologies: passive and active tags. Passive tags use the radio frequency from the reader to transmit their signal. Passive tags 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 an on-board battery for power to transmit their data signal over a greater distance. This also powers 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, this technology remains in a development mode.
