Description: How to use BlinkID as a barcode scanner only
---

# Scan barcodes

By default, BlinkID runs all four [extraction modules](scanning-settings.md).

To use BlinkID as a standalone barcode scanner, disable all the modules except `barcodeModule`.

When `documentCaptureModule` is disabled, additional barcode formats that are otherwise unavailable become enabled: UPC-E, UPC-A, Code 128, Code 39, EAN-8, EAN-13, ITF, Data Matrix, and Aztec.

:::note

`pdf417ScanningEnabled` and `qrScanningEnabled` must always be enabled or disabled together.

:::

## Configure the session

Disable `documentCaptureModule`, `mrzModule`, and `vizModule` by setting each to `null` (web, Android) or `nil` (iOS).
Leave `barcodeModule` enabled.

## Read the result

The barcode result is available on the per-side sub-result.
`barcodeData` contains the raw bytes and the decoded string.
For driver's licenses and other AAMVA-compliant documents, the barcode data is also parsed into structured fields.

{/* TODO: review the correctness of these fields */}

  <TabItem value="web" label="Web (TS)" default>

  ```typescript
  blinkId.addOnResultCallback((result) => {
    const side = result.subResults[0];

    // Raw barcode string
    console.log("Barcode string:", side.barcode?.barcodeData.stringData);
    console.log("Barcode type:", side.barcode?.barcodeData.barcodeType);
    console.log("Parsed:", side.barcode?.parsed);

    // Parsed fields (populated for AAMVA-compliant documents)
    if (side.barcode?.parsed) {
      console.log("First name:", side.barcode.firstName);
      console.log("Last name:", side.barcode.lastName);
      console.log("Date of birth:", side.barcode.dateOfBirth?.gregorian);
