Replacement: RTL-11506. We are now using blank cards without any writing on them. This page is for reference only.
Description: If you've been playing with RFID long enough, you know you can never have enough RFID tags! We've retail packaged a stack of five of our 125kHz RFID tags for when your RFID-protected secret clubhouse starts attracting more members (or whatever it is you do with RFID tags...)
These tags each have a unique 32-bit ID code and can't be re-programmed. You can read the codes on the tags with a 125kHz RFID reader, such as the ID-12 or the ID-20 which can be found in the related items below.
Dimensions: Each card is 2.13 x 3.35 x 0.03" (54 x 85.5 x 0.8mm)
