Using RFID Tags And ReadersProduct Overview
This is a simple, thumbnail-size RFID tag. Isn't it cute as a button? These tags are great for sensing presence, identification, and more, and they're small enough to be easily sewn into clothing or inserted into enclosures. 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 the ID-3LA, ID-12LA, and ID-20LA RFID reader modules.
We tested this RFID tag with one of our ID-12LA readers and measured a maximum read distance of about 32mm.
