Anyone successfully clone and write GOJO rfid Soap dispensor tag?

[Ikkilan]

Motive: Gojo soap refill is expensive.
Plus, throw away empty reusable plastic is not a good practive to me.
I tried to identify type of chip they use and find that it response to high frequency around 13.56 MHz.
I hope any senpai has experience in this field. Please share something, really appreciate it.

Do you have access to the card/fob.
If it is High Frequency, download TagInfo, scan the card/fob and share that here

How to share NFC chip data via TagInfo app

TagInfo is an app made by a chip manufacturing company called NXP. It does a decent job of determining the type of chip it’s talking to and fully scanning any accessible memory into a scan report. It also makes sharing information gathered easy, which makes diagnosing problems or answering questions about specific NFC tags one might have much more efficient.

Just rip them out and replace with non-proprietary dispensers. That’s crazy the refills are tagged. It’s friggin soap.

Taginfo seem like not work with this one. I used Proxmark3 to scan it at 13.56 MHz

Yes. I do have another one upstair which GOJO did not use the tag. I don’t any equipment to modify the sensor chip right now. Replace it will be an option soon.
