Ready-to-Use UI | Capacitor Barcode Scanner

We've improved the Ready-to-Use UI Components of our iOS and Android Barcode Scanner SDKs, which makes it even easier to provide your users with an intuitive scanning interface without having to build it yourself!

The Ready-To-Use UI (RTU UI) is an easy-to-integrate and highly customizable high-level UI component that can handle most barcode scanning use cases and tasks.

The design and behavior of this component are based on our many years of experience as well as the feedback from our SDK customers.

Although the main idea of the RTU UI is to provide simple-to-integrate and simple-to-configure components, its customization capabilities are numerous and should suit most of your needs.

Import

To use the RTU UI v2.0 component please import startBarcodeScanner function and all related configurations and results from capacitor-plugin-scanbot-barcode-scanner-sdk/ui_v2.

Example:

import { startBarcodeScanner, BarcodeScannerConfiguration } from 'capacitor-plugin-scanbot-barcode-scanner-sdk/ui_v2';
RTU UI v2 Default Configuration

Returns

  • result.status - OK If the scanning is completed, CANCELED if the user has canceled the operation (tapped on the "cancel" button).
  • result.data?.items - Optional List of recognized barcodes as items. See the barcode item structure below.

Barcode item structure:

  • type - Recognized barcode symbology.
  • count - Number of recognized barcodes of this symbology and value.
  • text - Recognized value of the barcode.
  • textWithExtension - Recognized barcode value with extension (if available).
  • rawBytes - Representation of the raw data that is contained the recognized barcode.
  • parsedDocument - The parsed known document format (if parsed successfully).

Change the visuals to suit your needs

In addition to a fresh new design, the RTU UI v.2.0 comes with new configuration options that enable you to quickly adapt its visual appearance:

Palette

Barcode sheet mode

The bottom sheet used to display previews of the scanned barcodes has two modes: COLLAPSED_SHEET and BUTTON. In COLLAPSED_SHEET mode, the bottom sheet is visible and collapsed and can be expanded by dragging it up. In addition, the button can show the overall barcode count.

Use cases

Single scan with confirmation dialog

alt text

The single scan mode is optimized for scanning single barcodes and easily configurable according to your needs. It comes with the option of showing a confirmation sheet after the barcode is scanned. The confirmation sheet is also highly customizable, offering the ability to configure the barcode title, the barcode subtitle, the cancel button, and the submit button.

Multiple scanning

alt text

The multiple scanning mode is very flexible and allows you to configure each component in several ways.

Firstly, it offers two display modes: one with a collapsed list of scanned barcodes and one with just a toggle button that brings up the list.

Secondly, there is an option to configure the counting mode. The counting mode can either be COUNTING or UNIQUE. In COUNTING mode, the scanner scans barcodes with the same value again and counts the number of items. In the UNIQUE mode, the scanner only scans barcodes with unique values. If another barcode has the same value, it won't be scanned again.

Additionally the countingRepeatDelay can be used to set the time interval in milliseconds that must pass before counting a barcode again.

Find and Pick scanning

alt text

Using the Find and Pick scanning mode, you can set a list of expected barcodes to be scanned. In the list, you can provide for each barcode its value, title, image, and count. The count simply means, the number of times a barcode needs to be scanned. You also have the flexibility of setting the allowPartialScan property of the use case to complete the scanning with partial results. The find and pick use case also makes it possible to provide an extensively elaborated visual experience using AR Overlays by providing the ability to properly distinguish between different barcodes (not expected, expected but partially or fully scanned). The bottom sheet is also highly customizable and provides information of the current state of the barcodes. You can also manually change the count of each barcode from the list, incrementally or by tapping the count and manually typing in the number.

AR Overlay

alt text alt text

The Barcode AR Overlay can be enabled to display and select recognized barcodes in an augmented-reality fashion. Each recognized barcode will be presented on the barcode overlay by a colored frame and text. The style of the frame and text can be customized for scanned and not-yet-scanned barcodes. Barcodes can be selected automatically or by tapping on the barcode overlay.

Display product information right in your scanning interface

alt text alt text

Some use cases require the data connected to a barcode's value to be displayed to the user directly. That is why we have added the option to visualize this data in the scanning interface. For example, you can show a product image next to the article number encoded by the barcode.

This feature is also available for the SDK's AR Overlay, making it even easier for users to identify a barcode's contents in real time.
