You reader is either a Secukey S1-X or Secukey
S1-R or a Secukey S1-RX.
S1-X: supports 125 kHz EM & HID tags - probably compatible with NeXT.
S1-R: supports 125 kHz EM & HID tags - probably compatible with NeXT.
S1-XR: supports 125 kHz EM & HID tags and 13.56 MHz Mifare Classic cards - probably also compatible with the NeXT.
Have you tried to scan your card with the NXP Taginfo app on Android? If it comes up, it’s probably a Mifare Classic, which is not compatible with the Next (would need the xM1). But since it is a multi-technology reader, you could probably still enroll your NeXT.
Is your Next already implanted? Edit: Yes it is. I saw your othe thread. If you try bringing your implant close to the reader, does the light on the reader also flash?
If you have access to your badge server, you could just try to enroll it yourself. Scan your implant with the reader and the number should show up. If you are lucky, the Next is already configured for the right emulation, otherwise, you will have to chamge it with the Proxmark.
In the clip you are scanning the diagnostic keyring. The reason why the xFD doesn’t send a number to the server is because it is just a passive led and an antenna - there is no actual chip in it that would communicate with the reader, it is just powered off its field.
Side note: Secukey is a strange company, not a lot about them, all datasheets/manuals are encrypted for some reason. That’s why I can’t give you more details.
