I got coffee maker and it uses Smart filter with rfid chip. After some long time use filter get expired and machine asks to replace new one (Why do i need replace them if i use filtered water)
I know that filter RFID data gets written and its impossible trick machine with used filter.
Its possible rewrite RFID data and trick machine its like new filter inside machine ? Some says its possible. Any help or tips would be nice
By the way phone reads that RFID data but cant do much without seeing what is inside
And filter i am using is Jura 72819 Claris Pro Smart Water Filter
Still, use NFC Tools on a phone, or HF search on the Proxmark3 to see what it detects. Knowing which chip is used by those cartridges would be very helpful.
Yes i have 1 dead filter and 1 fresh new one not used.
I did scan with iphone and dont have any android with RFID stuff.
I dont have reader and i dont know once it will arrive but i am curious if its possible just edit data or just use fresh one and duplicate data on dead filter ?
Try scanning with Android taginfo and export the fill scan text file. I can’t tell for sure but it looks like memory is not used here for this application. It looks like a standard vicinity tag.
If this is the case and no memory is used, then the coffee maker itself is storing the ID of the tag and keeping track of use. You should be able to just remove the tag and replace it with a different ID and it will think it’s a new filter.
I dont have any android device with NFC reading thing (too old device)
From reading this i feel like New filters dont have any data and once u insert new one machine just writes up data on it ?
Wont be enough wipe inside data and trick machine ?
I can’t really say one way or the other because the screenshots you posted above have no indication what tags were scanned. There is one clue that says the memory has zero bytes, but again I don’t know if this means there is actually no programmable memory or if there is just nothing programmed to the memory.
Android will give you much better data. If you can find an Android phone or borrow one and use taginfo on that phone, and post the full scan data for both tags and indicate exactly which tag is being scanned for each data set, we can then start to talk about confirming your speculation.
Yeah i understand you.. My whole family owns iphones and friends are far away.. Well i just wait for delivery and later here i try upload what i find interesting ^^
I understand. What about scanning both tags with taginfo on your iphone and posting which scans are which? I’m mostly curious about the “memory information” for both “fresh” and “dead” tags.
E0163C0613E5E39D has a manufacturer byte of 16 which is not NXP, it’s likely an EM-Microelectronic / EM-Marin Micro Tag. You can read about the chip spec here;
