There should be a command you can send that will re-activate the chip… I think I came across that in the documentation
What is the kill command hex code you are sniffing? Care to post the sniff log?

Thanks @amal ! As far as I know the kill command is irreversible based on manufacturer website. I can provide the hex code once I get my hands on another active chip.
Any experience at all with mutual authentication NFC protocols? This is where I would like to be able to use my own tags. Looks like it’s never shared unless someone acquires an icode dna chip from a supplier with a nda.
I think this is an icode DNA tag and i had a successful story on icode slix2. They are similar to each other.
@Ytosko Did you find a way to get the Device working? (I have the same device and am running into the same issue)
@amal I found this document explaining how to revive “killed” tags. https://ro.ecu.edu.au/cgi/viewcontent.cgi?article=1064&context=ism
Would that help to revive the Tag and reuse them?
The Lazarus Effect_ Resurrecting Killed RFID Tags.pdf (488.2 KB)
Not really the same issue… specifically iso15693 tags support something called EAS (electronic article surveillance) and AFI (application family identifier) which are used basically for making sure products aren’t stolen from stores… but can also be used for real-time inventory or checkpoint inventory… stuff like that.
Because of the concern about privacy with RFID tags being embedded into retail products, there is effectively a kill code built into these types of tags. The idea is that when you purchase the item, the tag is killed at point of sale rendering it inert when you walk out of the store with the thing you bought.
Unfortunately, there are such things as returned products… so RFID transponder makers included a way to revive these killed tags. Sometimes the vendor claims there is no revive features in a particular type of EAS tag, but security researchers have sound workarounds to revive these types of tags.
