# Barcode Scanner

[Zia Barcode Scanner](https://docs.catalyst.zoho.com/en/api/code-reference/zia-services/barcode-scanner/#BarcodeScanner) enables you to scan the most commonly used linear and 2D barcode formats and decode the encoded data. Barcode Scanner can detect formats like Codabar, EAN-13, ITF, UPC-A, QR Code, and more.

You can provide an input file of the format .webp/.jpeg or .png to the `open()` method. This method returns the image file object as a response. Refer to the [API documentation](https://docs.catalyst.zoho.com/en/api/code-reference/zia-services/barcode-scanner/#BarcodeScanner) for the request and response formats.

You can specify the barcode format using `setFormat`. If you enter the format as
`ALL`, Barcode Scanner automatically detects the format. It provides the decoded information as the
response.

To know more about the component instance `zia` used below, please refer to [this help section](https://docs.catalyst.zoho.com/en/sdk/python/v1/zia-services/get-component-instance/).
