Camera

The Camera element allows users to capture images directly within an application by utilizing the device’s camera. This element can be used for scenarios where image input is required, such as ID verification, document uploads, or capturing photos for forms.

Common Use Cases:

• ID Verification: Banks can use the camera element to capture customer IDs for KYC processes.
• Document Uploads: Allows users to snap photos of documents for submission.
• Profile Picture Capture: Customers can capture profile pictures for their banking profiles.

Its Configuration

The element’s configuration in vFlow 2.0 allows you to customize its behavior, appearance, and interaction across various devices. Through simple settings, you can control everything from its visibility and functionality to how it adapts to different screen sizes, making it flexible and user-friendly for developers and end-users. Let’s have a look at each of its configurations:

Basic

Basic Configuration	Description

Events

The Events option of the element allows you to assign task groups that will execute when specific actions occur on the element. These tasks can be created separately in the configurator or inventory and grouped to perform various actions when certain events are triggered.

Here’s a breakdown of the Events section:

1. Custom Load:
   • The Custom Load event enables you to trigger a specific task group during a customized loading scenario.
   • Similar to the previous options, you can choose the task group to be executed from the Select Task Group dropdown list or go back to the inventory or configurator to make a task or task group if needed.
2. After Upload:
   • This event is triggered after the element has been successfully uploaded.
   • It is often used to execute further actions, such as displaying a confirmation message, updating a visual element, or processing the uploaded content.

• Bounce
• Flash
• Pulse
• Rubber Band
• Handshake

Their Configuration:
Click the TYPE list, and then select an animation to apply an effect when the element loads.

After you select one of the animations (for example, Bounce), you will see the following configuration options:

• Speed: In this field, you can select one of the following options to adjust the speed of the animation:
  • Faster
  • Fast
  • Slower
  • Slow
• Delay: Click this list to select a value (for example, 3 seconds). This value specifies a time period. The application will load the animation after this time period (e.g., 3 seconds).
• Repeat: In this list, select a value (for example, 2). This value specifies the total number of times the application will play the animation.

After you configure the element’s animation properties, click to apply them to the elements.

Data

The Data section of the Camera element is where users configure data handling, service integration, and messaging for media-related tasks such as uploading, fetching, and deleting media files. It helps to streamline file management processes by integrating services and providing feedback mechanisms for users based on success or failure.

Key Fields:

1. Minimum Upload Size: Defines the smallest allowed size.
   • Minimum Upload Size Message: Displays a message if the image is below the specified size.
2. Maximum Upload Size: Sets the largest allowed size.
   • Maximum Upload Size Message: Displays a message if the image exceeds the maximum size.
3. Upload Success Message: Select a message to display when the media file upload is successful.
4. Upload Failure Message: Select a message to display when the media file upload fails.
5. DMS Services: These fields allow you to integrate Document Management Services (DMS) to fetch or delete media files.
   • Fetch MDO Service Name: Specify the service to use for fetching media data from an external source.
     • MDO (Master Data Object) is like a main reference for important information, such as customer details or product info, that an app or system needs to work properly. It helps keep everything organized and accurate by making sure everyone uses the same key data.
     • For example, in an online store, MDO could be a list of all the products, with details like product names, prices, and stock levels. This ensures that everyone using the store sees the same product information.
     • If you’re fetching an a document from an external source, MDO data might include the object’s key identifier, data type, and specific path within the external system, helping to retrieve or manage that object effectively. It’s often used in integration scenarios where master data is centrally maintained and needs to be referenced or used across multiple applications or services.
   • Fetch MDO Service Success Message: Choose a message to display when fetching MDO service succeeds.
   • Fetch MDO Failure Message: Choose a message to display when fetching MDO service fails.
   • There is an +add option. When clicked, it reveals three additional fields:
     • Fetch MDO Key (Textbox):
       This field allows you to enter the key that will be used to fetch MDO data.
     • Fetch MDO Value Type (Dropdown):
       This dropdown enables the selection of the data type for the MDO value. You can define how the value fetched will be interpreted based on the type.
     • Fetch MDO Value Path (Textbox):
       Here, you can specify the path from where the MDO value will be fetched, giving the exact location or path within the data.
   • Fetch Files Service Name: Specify the service for retrieving media files.
   • Fetch File Service Success Message: Choose a message to display when the file retrieval service is successful.
   • Fetch File Service Failure Message: Choose a message to display when the file retrieval service fails.
     • Note: A similar +add option is available as it was under MDO Service Options with the same function but related to file fetching instead of MDO.
   • Delete File Service Name: Specify the service for deleting media files.
   • Delete File Success Message: Choose a message to display when the file deletion service is successful.
   • Delete File Failure Message: Choose a message to display when the file deletion service fails.
6. Data Source
   • Data Type: Define the type of data source to fetch or manage media data. Options include predefined paths.

By configuring these fields, the image element can seamlessly integrate with external services and provide clear feedback to users regarding their media management action.
