Cross-Document Data Match Module
This guide is specific to Web SDK 2.0. If you are still using 1.x, you can find documentation here. Contact your Incode Representative for upgrade information and check if you are a candidate for this upgrade.
Full rollout to all clients still TBD.
The Cross-Document Data Match module runs a backend comparison of OCR data across multiple captured documents (e.g., ID + proof-of-address) and flags inconsistencies. Fire-and-forget — completes after a minimum display duration so the user sees a confirmation spinner.
Follows the backend-process pattern. See the patterns page for the shared lifecycle.
Tag
<incode-cross-document-data-match> is a standard Web Component. Importing the UI subpath registers the custom element; the module is bundled with @incodetech/web/flow (no separate UI subpath import).
import '@incodetech/web/cross-document-data-match';Properties
| Property | Type | Required | Description |
|---|---|---|---|
config | CrossDocumentDataMatchConfig | ❌ | No options |
onFinish | () => void | ❌ | Called when comparison completes |
onError | (error: string) => void | ❌ | Called when an error occurs |
Configuration
The module takes no configuration:
type CrossDocumentDataMatchConfig = Record<string, never>;Comparison rules and inconsistency thresholds are configured server-side per tenant.
State machine
CrossDocumentDataMatchState is a discriminated union over status:
| Status | Description |
|---|---|
idle | Initial state. |
processing | Backend comparison in progress. |
finished | Terminal — comparison completed. |
The module deliberately holds the processing state for a minimum display duration so users see a confirmation spinner regardless of how fast the backend responds.
