System Requirements



  • 64-bit Windows 10.
  • Minimum 4 GB RAM (For faster MIFARE Classic decryption, we recommend at least 8 GB RAM and at least 4 cores CPU).
  • 64-bit CPU and OS (All newer mid range to high end Android phones use 64-bit CPU and OS).
  • Minimum 4 GB RAM.
  • Android 8.0 and above (All newer Android phones come with at least Android 8.0).
  • Must have an USB-C port and able to supply enough power to peripheral devices. If you get communication error while working with HF tags, that means your phone is not supported. Working with the HID iCLASS tags draws highest current, we recommend you read an HID iCLASS tag a couple of times and make sure it's working. If it works, that means your phone is fully compatible. However if your phone has less than 4GB ram, the app may crash when you work with MIFARE Class tags. Below is the chart for known working ones and non working ones.

Tested fully compatible

Tested with known issues

  • Huawei P20
  • Google Pixel
  • OnePlus series
  • Xiaomi Mi 6 (may occasionally have issue with HID iCLASS tags due to phone's USB-C port cannot supply enough power to the reader)
