Hello,
I was wondering if anyone has seen this before?? Lf search comes back as two different formats C15001 and Sie36
proxmark3> lf sea u
NOTE: some demods output possible binary
if it finds something that looks like a tag
False Positives ARE possible
Checking for known tags:
HID Prox TAG ID: 3f09ea09b4
--------------------------------------------------
Format: C15001 (HID KeySpan 36-bit)
Facility Code: 245
Card Number: 1242
OEM Code: 900
Parity: Valid
--------------------------------------------------
Format: Sie36 (HID 36-bit Siemens)
Facility Code: 230645
Card Number: 1242
Parity: Valid
--------------------------------------------------
Valid HID Prox ID Found!
Valid T55xx Chip Found
Try lf t55xx ... commands

I expect this will be that the encoded data could be one of those 2.
Is either correct?

A lot of HIDs prox formats overlap eachother, making it impossible to tell the exact format just from the binary.

Marshmellow is correct. Since there's a lot of overlap in the vast number of formats out there, the parser attempts any formats it knows to see if it decodes properly and it returns those that do. If there are markings on the card, it might help to identify which format was intended.
Regardless of whether or not one of the two displayed formats was the intended decode, the HID Prox TAG ID line is correct. That is, ultimately, the data that was read from the card.
