Product Features

Read and write to RFID tags up to 6cm away. Supports EM4100 series, ISO11785 FDX-B and our own PhidgetTag protocols. Writes to T5577 tags.
Product Description

The PhidgetRFID Read-Write reads RFID tags that are brought in close proximity to the reader and returns the tag identification number. Writing data to T5577 tags is also supported.

RFID (radio frequency identification) systems use data strings stored inside RFID tags to uniquely identify people or objects when their tags 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 Read-Write supports reading and writing in 3 protocols; EM4100, ISO11785 FDX-B, and PhidgetTag. The PhidgetTag protocol simply stores up to 24 ASCII characters to the tag, eliminating the necessity for a table of corresponding tag numbers and names in your program. Phidgets sells EM4100 read-only tags that can be read with either of our RFID readers, and writable tags which can be written with the 1024 using any protocol. Any 3rd-party EM4100 or ISO11785 tags can be read.

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.

The 1024 has two digital outputs, labeled "+5V" and "LED". These work the same as any other Phidgets Inc. digital output, except that the "+5V" output has a higher current rating. You can use these outputs to have an LED or buzzer to indicate when a tag read has occured.
