I am trying to know what chipset this card is using , it doesnt respond to t5 , its an em asit shows but cant identify the chipset , is there any command to find the chipset ?
this is the results i get
[usb] pm3 → lf search
[=] Note: False Positives ARE possible
[+] Valid EM410x ID found!
[=] Couldn’t identify a chipsetpm3 →
other cards it can identify the chipset like this one
[usb] pm3 → lf search
[=] Note: False Positives ARE possible
[+] Valid EM410x ID found!
[+] Chipset detection: EM4x05 / EM4x69lf em 4x05 commands
Sounds like it’s an EM chip…
It’s probably an EM chip. Still, making sure that there’s good coupling between the Promax and the tag might give you slightly more positive results.
Edit now that I’m actually awake:
The EM4305 and EM4205 chipsets have very similar functionality to the T5577 . So you can write a different ID to it if you want.
Chances are that the first fob that the Promax if failing to detect a chipset on is a plain and simple EM4100 with a fixed ID.
In other words, the fob most likely has a EM4100 so the Promax isn’t detecting a chipset that can emulate it.

so there is no command or some way to find out exactly what chipset ist !!
You might start with trying lf em 4x05 info
What is your end-goal here? Are you trying to clone something to it?
didnt get any info from first card , the other one shows fine ,

I need to have same card for one access system , and i am unable to recognize it
I see, I didn’t realize you were working with multiple cards
So you are trying to clone something?
at first i didnt know they are different cards , but when i was testing and it didnt work then i found out they are not the same ,
i need to have same exact card so it will work in the system , ( i mean same chipset ) not cloning ,
why? the em4305, the underlying chip is an emulator chip, it’s emulating an em4100 with a chosen ID. why do you specifically need em4305, ordering em4305 doesn’t mean they’ll work with your system unless they’re encoded to work with the system.
if your system utilises the em4305 cascade past the initial ID being emulated (ergo storing more in the memory) they would be custom encoded and may have a password enabled
please provide more details about your situation as well as photos of the card and the device you use to add cards to the system and the readers on the wall.
also why can’t you buy more cards from the system manufacturer?

no , the system totally doesnt recognize that a card has been tapped , and its not limited on the manufacturer, i have an old card which is being recognized , but still the results i get is ( couldnt identify the chipset )
or could be the chip uses less power than the other one , maybe
Which of the two cards is the one that works with the system?

EM 410x ID 400054D637
the first one with (Couldn’t identify a chipset ) EM 410x ID 400054D637

It’s an EM4100. You can clone it to a T5577 and it’ll probably work.
