The PhidgetRFID reads RFID tags that are brought in close proximity to the reader and returns the tag identification number.
RFID (radio frequency identification) systems use data strings stored inside RFID tags or transponders) to uniquely identify people or objects when they are scanned by an RFID reader. These types of systems are found in many applications such as passport protection, animal identification, inventory control systems, and secure access control systems.
The PhidgetRFID (as well as the RFID tags sold by Phidgets) uses the EM4102 protocol. Any other tags that also use the EM4102 protocol can be used with the PhidgetRFID reader.
Because passive tags require a strong RF field to operate, their effective range is limited to an area in close proximity to the RFID reader. The distance over which the RFID tag is usable is affected by such things as the tag shape and size, materials being used in the area near the reader, and the orientation of the reader and tag in respect to each other and in their operating environment. The smaller a tag, the closer it must be to the reader to operate.
