Are you using your phone to read it?
Do this…
Do you have any other RFID tools?
Flipper Zero?
Proxmark?
Do you yse your phone for anything official on the Petkit tag?
ie. other than the app?
How do you get the information from it?
Do you scan it with the app to upload the data?
We might need to see a couple of data dumps.
one before the data has been uploaded and ine after.
I am not sure how this system works with NFC…
Are there specific readers? like a feeder? cat door etc?
Even then, that seems limited?
Do these have batteries?
Do you connect them with WiFi? but that would only be good at home…
What about Bluetooth? and it uses your phone through the app as a part of their eco system to upload data, but that requires you to be near your pet, which might work but with limitations…
Is there a sim card in it? is it IoT?
Hopefully somebody else here is familiar with this product.
Can you try and answer as many questions as possible, because im really not sure how this product works.
Otherwise ill have to google for some answers…
