Electra intercom

[andreivinca]

In Romania, there is a well-known brand of intercoms called Electra. The CU can detect its tag as EM410X, but the intercom does not respond to its emulation. In other words, the intercom does not react at all to the EM410X tag, and I've attempted using various tags from the same brand without success.

Another discussion involves individuals who have managed to make Electra work with Flipper. https://forum.flipper.net/t/electra-intercom/6368

Can this be applied to ChameleonUltra?

Did you try with the CU? It does support EM410X

[andreivinca]

Yes, that was the first step I took.

the proxmark3 supports it, not yet the cu. Electra format is a bit similar to EM4100 but with extra data. https://github.com/RfidResearchGroup/proxmark3/commit/ee22a824ce6ee0048245298b2ebba0be5fb02b6c

There is a more modern electra format which is discussed in that link.
The PM3 doesn't not identify that part yet.

I did add the cloning support. https://github.com/RfidResearchGroup/proxmark3/commit/c544d67d2bc7d49579da4e197ee50fa85a37343b

Could you work your magic for the CU as well?
