Contact me through Discord if you want the NFC Card number/ more screenshots. I don´t want to give it to the public.

It seems like f0 doesn't support writing operations on emulated card. So it will only emulate "frozen" card state, the reader will be unable to update emulated card's memory and the transaction will fail. By the way, this also affects intercoms in my area: reader writes new data on each pass, if it is unable to write - key is declined.

can it be fixed by an firmware update? because some guys here said its broken with newer firmware:https://forum.flipper.net/t/flipper-zero-can-read-cards-but-cant-emulate-them/20006

[mxcdoam]

It might be not broken, but intended that way. Storing backups of transit passes on a pocket device might sound like a nice idea, but it usually goes against most transit authorities rules of service. As for the intercom keys - I am curious too if this is possible or not.

Yeah sure. I mean, once its expired, It will also not work anymore. So it doesn´t matter.

maybe this helps. They do have this symbol.

[skotopes]

@Killer74-hub try to use any other tool you can find. For example mobile phone apps for nfc or any other reader. They may be using different detection technic and give some hints on card type.

[Killer74-hub]

I found it. it´s a: Mifare SmartMX I think

I have NFC Tools. I will try it right now

[skotopes]

We don’t support smarts yet. We will take a look as soon as get some systems with it in our hands.

wait. Its not I think. My app says something different

[Killer74-hub]

Can I send it to you on Discord? Or is it safe for here?

[skotopes]

Yes you can find me on discord, search for skotopes.

[skotopes]

But keep in mind that @gornekich is nfc maintainer and you probably want to talk with him instead.

[Killer74-hub]

oh ok. I´ve sended it to you. Does @gornekich also have discord?

[skotopes]

Yes, but please ping him on Monday. He deserves some weekends.

[Killer74-hub]

Yes, but please ping him on Monday. He deserves some weekends.

Alright. np. I cannot find him on Discord. what is his username?

[skotopes]

He’ll tell it on Monday.

[Killer74-hub]

He’ll tell it on Monday.

Ok. Thank´s for your support here. I appreciate it!

Hey @Killer74-hub . Thanks for information. We will get this card and start working on its support. However, I read datasheet and it's look like it is a well secured card, so flipper will read open data but full emulation might be impossible.

Hello! Thank´s for your reply @gornekich . It might be a Mifare SmartMx. But I don´t think so. Could I send you the screenshot that I have sended @skotopes on discord? If so, what is your discord Name?
