Could you please give more info on the card?

• Please provide the logs of the reading process (more on gathering logs here).
• Could it be read with 0.93? If so, it would help if you posted the logs and a save file of it.
• Is it the only NFC-B card in your posession? If not, can other NFC-B cards be read?
• How does it look like? Does it have a manufacturer brand on it or other identifying text?
• Can you read it by other means? (Phone, specialised reader, Proxmark etc - any additional information on the card will be helpful).

With 0.93 the device read the UID of the card.

I have only one NFC-B card (ISO14443B) and i can read it with my pc (uTrust 3700F +Cardpeek) and with my Android smartphone.

Hello @ronny17 !
Looks like that Flipper can't parse ATTRIB response. Could you please share data that your Android smartphone or pc can read? The ATTRIB response is what we need to see

Using nfc-list I get this

@ronny17 There are some updates on iso14443-3b poller logic arived in #3264 . Since we can't reproduce this issue, we need your help with testing. Could you please update flipper on latest RC or dev, read your card and provide logs as before.

[ronny17]

I've updated my flipper to 0.96.1-rc and these are the logs
340384 [D][Nfc] FWT Timeout
340413 [D][Iso14443_3bPoller] Incorrect CID in ATTRIB response: 80

[gornekich]

Thank you very much. Unfortunately your card doesn't follow iso14443-3b standard. We will make flipper read these type of cards, but in next release. Need some time to think how to implement it better. I will let you know once we make changes.

Hello @ronny17 !
I believe #3285 fix the issue. It would be very helpful if you test that PR and confirm that your card is read successfully

[ronny17]

Now my card is read successfully
Thanks
