Occasionally force closing. Using external reader. Read the tag then while try to view the tag force close. Using ACR122U reader by ACS. Fast response by the developer with assistance on the proper use of the software. 4 stars because it still force closes sometimes when trying to read a card.

Hello there, Which external device you're using? And did you put correct keys for that sector? --------- You have to learn the structure of Mifare 1k card. Each sector has keys to read and write. Before that, you need to crack the keys of all sectors on pc.

What's new

[Add] Support exporting dump file.
[Add] Support UID Changeable NTAG.
[Add] ACR122U card identifier.
[Fix] Crashing while using ACR122U on Android 12.
