I purchased the highly-recommended PicoPass 2K card from Red Team Tools so I could copy my iClass Legacy card to it. However when I got the card, I noticed that the card has “HID SEOS” written on it and the canonical instructions for writing to these cards failed and my proxmark3 fails to identify it as an iclass tag.
As far as I can tell these SEOS cards are not compatible with the PicoPass cards that I thought I was buying. Do I need to purchase something else or am I going about this the wrong way?
Just heard from RedTeamTools and they’re going to replace the cards, which I’m happy to hear. Hopefully you got the email too @vepr. (edit: should have read the most recent posts before replying, glad to hear you got the email)
With regards to emulation with JavaCards, I saw the following quote about the SEOS cards on this website which made me think that emulation of iClass Legacy cards on an iClass SEOS might be possible. I still don’t understand exactly what that mechanism would look like.
Best of all, Seos access control cards can specify other technologies such as MIFARE and DESFire, as well as HID legacy ranges such as Prox and older iCLASS cards.
This thesis has some good information about SEOS cards. Hain also has some code on github which is targeted at emulating a SEOS card with a JavaCard.
