125kHz Card Not Reading - Images and Raw Files Attached

[davewilliamstx]

Description of the feature you're suggesting.

Have tried two different versions of this card, not reading on Flipper. I'm not sure on source of the cards, our HOA uses them.

Unknown RFID Card.zip

Anything else?

No response

Yep this one is RFID, payload ASK coded, should be totally doable.

The reading using flipper-raw-rfid from .ask looks similar to #3336
100000000011010010111111111111111111111011110011011100111011000011011010010111111111111111111111
Inverting it and parsing spacers gives wiegand 26-bit format

f deontes facility code and c denotes card id. In this case card id is 1010001100100111 which is equal to 41767 in decimal. The same card number as printed on OP's card.

Also long pulses are around 330 mu sec given by Flipper Lab's pulse plotter. Close enough to RF/40 clock which would give 320 mu sec.

I'm not sure if inverting is intentional or if it is my mistake in analyzing the signal. If it is intended to be like the second sequence, then my PR #3697 should enable support for this card as well.

@davewilliamstx : do you mind taking a photo of the reader? It might help confirming the brand and protocol of this card.

Sure thing, it’s pretty beat up - hope it helps.

Thanks! I'm not sure if the image got through from email replies to the comment section. Would you mind upload it on github directly?

[davewilliamstx]

Ah, drat - here it is again. Cheers!

[zinongli]

Ok I'm pretty sure that's a securakey radio key reader. Should be supported once my pull request above passes through, fingers crossed.

In the meantime, if you toggle on Debug Mode, you should be able to read raw and emulate raw. I've heard of successes with securakey raw emulations. Maybe it works in your case too.

Fixed in #3697 thanks to @zinongli
