This RFID tag encased in a glossy white plastic card fits conveniently into a wallet and is ideal for access control or member tracking applications.
This is a blank tag- its ID must be chosen and written using the 1024 - PhidgetRFID Read/Write or another reader capable of writing to blank tags. It cannot be read with the 1023 - PhidgetRFID unless it has already been written as an EM4100 series tag.
This tag can be read by any of the RFID readers in the table below. Since this is a writable tag, it must have a tag string written to it at least once before it can be read. It supports the EM4100 series protocols, ISO11785 FDX-B, and our own PhidgetTag ASCII protocol. If you're using a different RFID reader, make sure it's designed to work at 125 kHz and supports one of this tag's protocols. For more details about the different protocols, see the user guide for your RFID reader.
