UHF RFID Tag (Set of 5)

Ever wanted to play with those newfangled RFID tags? Although it's been around for a while, the technology has been extremely cost-prohibitive and difficult to implement without being an RF engineer. This affordable product opens the door for using RFID in your own projects!

These paper-thin EPCglobal Gen2 tags work with our Simultaneous RFID reader. The tags can read and be written to --- and also have a kill feature. Each tag comes with a TID (Truly Unique ID) that can't be changed, but there's plenty of memory for you to write and read from.

  • EPCglobal Gen2 and ISO/IEC 18000-6c
  • 800 Bits of Memory
  • 512 User Bits
  • 64-Bit Unique TID (unalterable serial number)
  • 32-Bit Access and 32-Bit Kill Passwords* Width: 1cm
  • Length: 7cm

    Is this product available? What to use with the M6E board if this product is not available? Any alternatives ?

    Is it possible to have sticker-like tags like these for the ID-20LA reader?

    Hi, The tags are working great. Nevertheless I will have to design an enclosure since it will be hanging attached to a collar for animals. Do you have a recommendation, from your response a plastic with a tape will not work since the outdoor conditions and warm weather doesn't get along with glue. This will be for an animal identification, thinking about a putting this on a collar... :) Thanks

    I have tested these tags with the SparkFun Simultaneous RFID Reader - M6E Nano and they work great.

    Hi, I m building a project with UHF RFID technology and I m having problems with coke bottles and metals. Does this tag support beaing read while it is in bottles and metals?

    Thanks for your attention.

      Metals and liquids cause interference issues with these tags. What kryptonite is to Superman, materials such as metals and liquids are to RFID. They diminish its tracking powers by interfering with the strength and range of the tag's RF signal. http://www.inboundlogistics.com/cms/article/metals-and-liquids-rfid-kryptonite/

    Two questions- 1. Silly one but just confirming : Is this Passive tag? 2. Can you suggest me any cheap reader for this module? 200$ is expensive for me to afford.

    How thick are these?

    These tags can work in 125Khz RFID module RDM6300?

  • MIne are not on a white backing rather it's a clear substrate and it does not seem possible to peel them off. Are you saying just the metallic and chip peel off. Doesn't seem possible.

    • CF / about 7 years ago * / 1

      My mistake, I was looking at the other tags that peel off the white backing. For this tag, just cut between them leaving the foil antenna sections untouched and you should be OK.

  • Stupid question but one is to cut these out of the 5-pack and are the small bits of print separate from the main body at the extreme ends of each tag important to maintain?

    • CF / about 7 years ago / 1

      The entire foil section of these peel away from the white backing. You don't need to cut them, but can if you want to. Just don't cut anything metal.

    Water proof, water resistant ?? I would like to tag 100 - 200 swimmers as they come out of the water and cross the finish line. The swimmers are funnelled into a 4 foot wide gate where the RFID reader will be located on the top of an arch with a high gain antenna. So, would these tags withstand being submerged??


    • CF / about 7 years ago / 1

      Yes, these can withstand being submerged. In fact, you can read them while submerged, but the read range will decrease. I just tested one inside a glass of water and it reads just fine! It might be best to cover them in tape just to be sure though. I don't know how long they can withstand being under water.
