Signature Background Removal (Document Workflow)

Signature-focused background removal for scanned or photographed documents, producing clean transparent PNG output while preserving thin strokes and ink texture.

Key technical highlights

  • Stroke-preserving extraction tuned for signatures (fine lines, low contrast, uneven lighting)
  • Noise cleanup and edge refinement to avoid jagged artifacts and broken strokes
  • Export pipeline to transparent PNG with consistent sizing and background neutrality
  • Designed for document workflows (forms, PDFs, e-signature stamping, back-office automation)

NXP P71 — SCOSTA CL Card Personalisation (Windows)

Windows desktop application for SCOSTA CL smartcard personalisation workflows on NXP P71, supporting reliable data writing and provisioning steps.

Key technical highlights

  • Card personalisation flows: data writing, file/record updates, and controlled sequencing
  • Secure-element (SE) creation/provisioning workflow support (as required by deployment)
  • Operator-friendly UI with predictable status reporting and failure handling
  • Protocol-aware communication patterns suitable for smartcard integration scenarios

NFC — NXP Ultralight EV1 Writer & Protection (OmniKey 5022, Windows)

Windows application for NXP Ultralight EV1 tag operations using an OmniKey 5022 reader, supporting data writing and password protection workflows.

Key technical highlights

  • Data writing with structured content layouts and validation before commit
  • Password protection setup and protected access workflows (Ultralight EV1)
  • Authentication flows to verify tag state and enforce protected reads/writes
  • Reader integration optimized for OmniKey 5022 in Windows environments

Note: Standard NXP Ultralight does not support password protection; this project targets Ultralight EV1.

Security note

For NFC/Smartcard systems, identifiers alone may not be sufficient for strong authentication. Where higher assurance is required, systems can incorporate cryptographic challenges, secure elements, and server-side verification strategies appropriate to the threat model.
