The RFID Keyfob is made from ABS in purple/white. Ideal for attaching keys. It supports the common 125KHz Hitag S256 standard. Size is 53x37.5x9.8mm.

This RFID tag has 256 bits of user memory. This enables the tag to carry around data that can be used to tell the reader what actions to take. The data could indicate the value of money or drinks remaining on the tag. You could just as easily program the data to indicate which doors are opened by the tag.

If you are looking for a tag without memory please look at those using the TK4100 transponder from CognIoT. Other tags are available from the CognIoT store on Tindie. Details of the tags can be found at http://www.cogniot.eu/125KHz_Tags.html.
