This is a simple, thumbnail-size RFID tag. These tags are great for sensing presence, identification, etc., and they're small, so they can be easily sewn into clothing or inserted into enclosures.

  • Diameter: 16mm

  • Thickness 1.85mm

Each tag comes with a unique 32-bit ID code and is not reprogrammable. The carrier frequency of this tag is 125kHz, so it works great with our ID-2, ID-12 and ID-20 RFID readers.

We tested this RFID tag with one of our ID-12 readers and measured a maximum read distance of about 32mm.
