Ever changing serial number on 1 tag

Hi, Friends!

Got an odd one - I was hoping someone could help me identify what type of card I’m dealing with, and how the serial number changes with each scan. The following images are taken right after each other with the same card…

Thanks in advance!

Grab the tag info app and scan it in there :wink: will tell you exact tag type usually

Thanks, way better!

Right there’s the answer, the desire chips are a “security” chip on of the functions is a “random uid”

If your on the discord server pop into the docs channel the datasheet for the ev1 is there.

@Devilclarke oh cool, I’m not - do you have an invite link I could use please? :slight_smile:
