Parsing KTP (e-KTP) Challenges

Indonesian KTPs present several OCR challenges. Firstly, inconsistencies in formatting and layout across different regions are common. Secondly, the presence of native Bahasa Indonesia text combined with varying print quality makes accurate text recognition difficult.

Why StructOCR for Indonesia

Our model is specifically trained on a large dataset of Indonesian KTPs, addressing layout variations and native text recognition, making it ideal for id card parsing tasks. The Python SDK simplifies integration by providing a straightforward API for efficient information parsing, allowing you to process images with just a few lines of code.

Common Use Cases in Indonesia

  • Digital Onboarding: Verify users for Fintech apps in Indonesia.
  • Telecom Registration: Automate SIM card registration with KTP (e-KTP).
  • Hotel Check-in: Speed up guest registration workflows.
