Biometric

The Biometric element enables applications to integrate and utilize biometric data, such as fingerprints or facial recognition, for secure identification and verification. It’s particularly beneficial in banking applications, ensuring high security and streamlining the login or transaction authorization processes. This element is designed for seamless integration into financial services, offering banks a way to enhance security while improving customer experience.

Common Use Cases:

• User Authentication: Verifying user identity using fingerprint or facial recognition.
• Secure Access Control: Facilitates secure access to sensitive sections of the application, like user profiles or confidential data, based on biometric validation.
• Transaction Authorization: Enables users to authorize high-value transactions or sensitive operations, ensuring an additional layer of security.

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
Type	The Type indicates the type of you are adding. In this case, it defaults to “Biometric” and cannot be changed here. This selection is made initially when you first create the element.
Reference Name	The Reference Name is a unique identifier assigned to the element for internal use. This name is visible only to vFlow users, and is not displayed to end-users. The Reference Name is intended for your convenience, helping you easily identify and manage the element throughout.
Label	The Label is the name or text displayed on the element, making it easily recognizable to end-users.
Description	The Description field is intended for use by application designers or administrators (vFlow users) to provide additional context or details about the element. This description is not visible to end-users and is used solely for internal reference to assist with element management.

Properties

Properties	Description
Visible	To make this invisible, click to clear this checkbox.
Enable	To disable the element, click to clear this checkbox.
Mandatory	If checked, this element becomes necessary to continue or for the workflow, enforcing user interaction before proceeding.
Default Value	This property allows you to display a predefined static value as the default text within the element. When there is nothing to show, the default value will be shown. This can be useful for providing placeholders or instructions to users.
Leading Icon & Type	It’s an option to add an icon or image before the element to indicate its purpose. You can select among None, IMAGE, and MATICON. You can also choose its Background and Text Colors.
Trailing Icon & Type	You can add an icon or image after the element, enhancing the field’s visual guidance. You can select among None, IMAGE, and MATICON. You can also choose its Background and Text Colors.
Tooltip	After choosing the Leading or Trailing Icon, you can enter a text that is visible while hovering the mouse over the icon without cluttering the interface.
Count / Path of Count	Count: This property allows you to display a numerical indicator next to the icon. It is useful for showing notifications, such as the number of unread messages or alerts. Path of Count: You can specify a data path from which the count will be dynamically retrieved. This ensures that the displayed count reflects the current state of the data, making the interface more responsive and informative. You might set the Path of Count to something like getVal("user.unreadMessages"), which retrieves the current count of unread messages from the user object.
Read Only	Selecting this will display content without allowing user edits.
Parent	Checking Parent will make this element a parent element, meaning it will take up the entire screen assigned to it until an event is performed. Once an event occurs, the screen will split to display both the parent element and the result of the action, providing a dynamic interface that adjusts based on user interaction.
Finger Type	Choose among fingerprint options: fmr(0), Fir(1), Fmr+fir(2)
Finger Count	Specify from 0 to 10.
Iris Count	Options include None, or a count from 0, 1, 2.
Api Version	Options are None or 2.0.
Timeout	Specify a timeout for interactions.
Finger Position	Select the position as Unknown.
Environment	Choose from Pre-Production, Production, or Staging environments.
Wadh	WADH (Whitelist Authentication Data Hash) is a security parameter used in biometric systems, especially in Aadhaar-based authentication in India. It is a unique hash value that links a biometric device with a specific application or service, ensuring that only authorized devices can capture and submit biometric data for authentication. It is generated based on specific application details and is used to verify the authenticity of both the device and the application, adding a layer of security to biometric transactions.

Style

The Style option allows you to personalize the appearance of the element. This includes adjusting various visual aspects to ensure it complements your application’s overall design. Here’s a breakdown of different settings that you can make adjustments to:

• Laptop/Desktop width: The button automatically expands to take up 100% of the available width on desktop and laptop screens, ensuring it spans the entire container. However, this width can be adjusted according to the specific design or layout requirements.
• Tab width: On tablet devices, the button will also span 100% of the container’s width. This ensures that it adapts well to medium-sized screens, making it easier for users to interact with on touch devices. You can adjust this width as needed based on design preferences.
• Mobile width: For mobile devices, the button remains at 100% width to ensure full visibility and easy tap interaction, even on smaller screens. Like the other devices, this width can be adjusted as per requirement.

Data Style

• Background Color: To choose the background color for the element, you can use a color picker or enter a hexadecimal or RGB color code. The default opacity is set to 100%.
