NFC Reading Issue with ISO 14443-3A Mifare Ultralight Card

Author: suaveolentCreated Feb 12, 2025Updated Jul 2, 2026
LabelsFeature RequestNFC

Describe the bug.

When attempting to read an ISO 14443-3A Mifare Ultralight card (ATQA: 0x0044, SAK: 0x00), the Flipper Zero device gets stuck on the "Don't Move" screen. The debug output indicates multiple FWT timeouts and failures in reading the ATS and signature from the card.

If I read it as "Specific Card Type" and select ISO14443-3A is correctly identifies the UID, however shows it as ISO14443-3A (Unknown)

Reproduction

  1. Attempt to read above mentioned ISO 14443-3A Mifare Ultralight card with the NFC application
  2. Observe the device getting stuck on the "Don't Move" screen.

Target

No response
