About these tools

These tools are part of an open research archive documenting how the Malaysian MyKad identity card works — its format, the hidden ISO 7064 Mod 11,2 checksum algorithm, chip-reading via APDU commands, and OCR research. Everything is compiled from publicly available sources.

For the full technical reference, complete documentation, source code, and credits, visit the GitHub repository.

Disclaimer: The checksum algorithm has never been officially confirmed by JPN (Jabatan Pendaftaran Negara). It was reverse-engineered by community researchers. A passing checksum does not mean the IC belongs to a real person — it only confirms the internal math is consistent. Do not use as sole means of identity verification. Example IC numbers shown in these tools are fictitious.
