I can help with that. For a lending workflow, signature capture usually means one of these:
- Typed signature — user types their name, rendered in a script font
- Drawn signature — user signs with mouse/finger/stylus on a canvas
- Uploaded signature image — user uploads an existing image
- E-sign + audit trail — signature plus timestamp, IP, consent text, document hash, etc.
A good implementation typically includes:
- A signature pad component
- Consent/acknowledgment text before signing
- Clear / redo controls
- Validation that signature is present before submission
- Storage of the signature as either:
- SVG/PNG image
- Base64 blob
- Stroke data for replay/audit
- An audit log for compliance
If you're building this on the web, a common approach is:
- Frontend: HTML canvas or a library like
signature_pad - Backend: store the signature file/blob and metadata with the loan application record
If you want, I can give you one of these next:
- a React signature capture component
- a plain HTML/JS example
- a backend API design
- a compliance checklist for e-signatures in lending
- a full end-to-end workflow
