Cards

The card component allows you to show your customers their different cards, and allows them to manage the cards lifecycle:

Reveal card information
Activate card
Set / Change PIN
Freeze / unfreeze
Replace a damaged card
Report card lost/stolen
Add card to mobile wallet (only iOS, Android, or React Native)

Security & PCI Compliance

The Card component is designed to minimize your PCI compliance burden by isolating sensitive card data (PAN, CVV) from your application code and infrastructure.

How It Works

Web (iframe isolation):

Sensitive card data renders inside a cross-origin iframe served from Unit's secure domain
The browser's Same-Origin Policy creates a security boundary that prevents your JavaScript from accessing iframe contents
Session recording tools (e.g., LogRocket, FullStory), error tracking, and analytics running in your parent page cannot capture data inside the iframe
This is the same mechanism that prevents malicious websites from reading your Gmail or online banking sessions

Native SDK (iOS, Android, React Native):

Sensitive data renders in secure SDK contexts using platform-specific isolation mechanisms
Your application code never receives raw PAN/CVV values - only tokenized references
The SDK handles all sensitive data display and user interaction internally

Scope-Based Access Control

Access to sensitive card data is controlled through customer token scopes:

Scope	What It Allows
`cards`	Read card metadata (last 4 digits, status, limits, expiration month/year)
`cards-write`	Freeze/unfreeze, report lost/stolen, replace card
`cards-sensitive`	Reveal full PAN, CVV (requires 2FA by default)
`cards-sensitive-write`	Set/change PIN

When generating a customer token, you specify which scopes to grant. Without cards-sensitive scope, the component will not render sensitive data even if a user requests it.

Upgradeable scopes: You can issue tokens with base scopes (e.g., cards) and upgrade to cards-sensitive after the user completes 2FA, avoiding pre-authorization of sensitive access.

// Example: Generate token with upgradeable scope
const response = await fetch('https://api.s.unit.sh/customers/123/token', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${orgToken}`,
    'Content-Type': 'application/vnd.api+json'
  },
  body: JSON.stringify({
    data: {
      type: 'customerToken',
      attributes: {
        scope: 'cards cards-write',
        upgradableScope: 'cards-sensitive'  // Can upgrade after 2FA
      }
    }
  })
});

Example:

import React from 'react';
import { UNCardComponent, UNCard } from 'react-native-unit-components';
import { NativeModules } from 'react-native';
const { PushProvisioningModule } = NativeModules;


export default function YourComponent() {
  return (
    <UNCardComponent
      cardId={'632197'}
      onStatusChanged={(card: UNCard) => { console.log(card) }}
      onCardActivated={(card: UNCard) => { console.log(card) }}
      pushProvisioningModule={PushProvisioningModule}
      onLoad={(response: UNComponentsOnLoadResponse<UNCard>) => { console.log(response) }}
    />
  );
}

Incoming Events:

In some cases, the default menu button won't fit into the design of an application. By using the openActionsMenu() method, it's possible to open the card actions bottom sheet from a custom button.

Important Note: one can use the openActionsMenu() only after UNCardComponent is loaded. (can be verified by onLoad callback)

Example:

import { UNCardComponent, CardRef } from 'react-native-unit-components';

...

const cardRef = useRef<CardRef>(null);

...

const openActionsMenu = () => {
  cardRef.current?.openActionsMenu();
};

...

<UNCardComponent
  ref={cardRef}
  cardId={"4242"}
/>

It's also possible to create your own menu and call card actions from it. Use openAction(action: UNCardMenuAction) method and send inside an action you want to perform. Use API Docs in order to understand which actions could be applied for any particular card statuses.

Example:

import { UNCardMenuAction } from 'react-native-unit-components';

// .......

const openAction = (action: UNCardMenuAction) => {
	cardRef.current?.openAction(action);
};

// .......

You can choose to implement your own show / hide card sensitive data button. In this case use 'showSensitiveData()' method to show sensitive data and 'hideSensitiveData()' method to hide it.

Example:

// .......

const showSensitiveData = () => {
	cardRef.current?.showSensitiveData();
};
const hideSensitiveData = () => {
	cardRef.current?.hideSensitiveData();
};

// .......

Add card to wallet

This capability can be used with the Card Component, or without it, as a separate flow. Complete the add to wallet guide for React Native, skipping the last module access from javascript, to use this capability.

Adding a card to Wallet with the Card Component

After completing the instructions to use this capability, pass the PushProvisioningModule as a prop to Unit's Card Component. This will let the SDK get wallets and start card provisioning for you once the native Add to Wallet button was pressed. Then, you can add a card to the wallet using the "Manage Apple Wallet" or "Manage Google Wallet" tab in the Card Components's native menu or using an AddToWallet as the Incoming event action.

Add card to wallet as a separate flow

After completing the instructions to use this flow, call UnitComponentsSDK.setPushProvisioningModule(PushProvisioningModule) with your PushProvisioningModule Native Module. After that, you can add a card to Apple or Google Wallet by calling the Unit SDK's startPushProvisioning(cardId: string, customerToken: string).

Example:

UnitComponentsSDK.ui.flows.startPushProvisioning(YOUR_CARD_ID, YOUR_CUSTOMER_TOKEN);

Android SDK

Component name: UNCardComponent

getCardComponent parameters:

Name	Type	Required	Description
cardId	String	YES	Unit card id.
additionalSettings	UNCardViewSettingsInterface	NO	Additional settings unique for this component
theme	String	NO	A URL that specifies the UI configuration.
language	String	NO	A URL that specifies the language configuration.
callbacks	UNCardComponentCallbacks	NO	Component's Callbacks sealed class

UNCardComponentCallbacks

The callbacks parameter for UNCardComponent is of the following type:

typealias UNCardComponentCallbacks = (callback: UNCardComponentCallback) -> Unit

The UNCardComponentCallback is sealed class that has the following callbacks that you can receive from a Card component:

sealed class UNCardComponentCallback {
    data class OnLoad(val onLoadResponse: Result<UNCard>): UNCardComponentCallback()
    data class CardStatusChanged(val card: UNCard): UNCardComponentCallback()
    data class CardActivated(val card: UNCard): UNCardComponentCallback()
}

To get the Card Component fragment, call the getCardComponent method of UnitComponentsSdk.manager.ui.views.

Example:

import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.fragment.app.Fragment
import co.unit.un_components.api.UnitComponentsSdk
import co.unit.un_components.common.builders.UNCardViewSettingsBuilder

import co.unit.un_components.components.UNCardComponent
import co.unit.un_components.common.models.UNCard
import co.unit.un_components.common.models.UNCardMenuAction

class CardFragment : Fragment() {
    private var unCardComponent: UNCardComponent? = null

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val fragmentLayout = inflater.inflate(R.layout.FILE_NAME, container, false)

        // Define your callbacks
        val callbacks: (UNCardComponentCallback) -> Unit = { callback ->
            when (callback) {
                is UNCardComponentCallback.CardActivated -> handleCardActivated(callback.card)
                is UNCardComponentCallback.CardStatusChanged -> handleCardStatusChanged(callback.card)
                is UNCardComponentCallback.OnLoad -> handleOnLoad(callback.onLoadResponse)
            }
        }

        // Check if this is a fresh creation or restoration after process death
        unCardComponent = if (savedInstanceState == null) {
            // Fresh creation - create new component and add to fragment manager
            UnitComponentsSdk.manager.ui.views.getCardComponent(
                cardId = YOUR_CARD_ID,
                theme = YOUR_THEME_URL,
                language = YOUR_LANGUAGE_URL
            ).also {
                childFragmentManager.beginTransaction()
                    .replace(R.id.CONTAINER_NAME, it as Fragment, FRAGMENT_TAG)
                    .commitNow()
            }
        } else {
            // Restoration after process death - find existing fragment by tag
            childFragmentManager.findFragmentByTag(FRAGMENT_TAG) as? UNCardComponent
        }

        // Set callbacks after obtaining the component (required for both fresh and restored)
        unCardComponent?.callbacks = callbacks

        return fragmentLayout
    }

    // ...
    // Event handlers
    // ...

    companion object {
        private const val FRAGMENT_TAG = "card_component"
    }
}

Incoming Events:

In some cases, the default menu button won't fit into the design of an application. By using the openActionsMenu() method, it's possible to open the card actions bottom sheet from a custom button.

Important Note: one can use the openActionsMenu() only after UNCardComponent is loaded. (can be verified by onLoad callback)

Example:

unCardComponent.openActionsMenu()

It's also possible to create your own menu and call card actions from it. Use openAction(action: UNCardMenuAction) method and send inside an action you want to perform. Use API Docs in order to understand which actions could be applied for any particular card statuses.

Example:

import co.unit.un_components.common.models.UNCardMenuAction

// .......

unCardComponent.openAction(UNCardMenuAction.Freeze)

You can choose to implement your own show / hide card sensitive data button. In this case use 'showSensitiveData()' method to show sensitive data and 'hideSensitiveData()' method to hide it.

Example:

  unCardComponent.showSensitiveData()
  unCardComponent.hideSensitiveData()

The additionalSettings parameter for UNCardComponent has this attribute:

UNCardViewSettingsInterface

Name	Type	Default Value	Description
hideActionsMenuButton	Boolean	false	Hide menu button in case value is true.
hideCardTitle	Boolean	false	Hide card title in case value is true.
hideSensitiveDataButton	Boolean	false	Hide sensitive data button in case value is true.
showCardTypeSubtitle	Boolean	false	Enabling will display the custom card type in the title.
showCardHolderSubtitle	Boolean	false	Enabling will display the custom card name in the title.
enablePushProvisioning	Boolean	false	Enables Push Provisioning in case value is true.
learnMoreUrl	String	""	A “Learn more” URL on the report lost/close card info note.
fee	Double	null	Fee for the card
menuItems	`List<UNCardMenuItem>`	null	A list of actions, The menu dynamically adjusts based on the provided list `[.Freeze, .AddToWallet, .ManagePin, .Replace, .Report, .Close]`.

You can use UNCardViewSettingsBuilder() to create an instance of the interface and define your additional settings.

val additionalSettings = UNCardViewSettingsBuilder()
    .fee(...)
    .learnMoreUrl(...)
    .hideCardTitle(...)
    .hideActionsMenuButton(...)
    .hideSensitiveDataButton(...)
    .showCardTypeSubtitle(...)
    .showCardHolderSubtitle(...)
    .enablePushProvisioning(...)
    .menuItems(...)

unCardComponent = UnitComponentsSdk.manager.ui.views.getCardComponent(
    cardId = YOUR_CARD_ID,
    additionalSettings = additionalSettings,
    theme = YOUR_THEME_URL,
    language = YOUR_LANGUAGE_URL
)

Set Unit SDK with the UNVisaProvider

Call UnitComponentsSdk.manager.services.setVisaProvider with a UNVisaProvider instance. It is recommended to call it in the onCreate method of your main activity. You will need to make sure you're initializing the UnitComponentsSdk with UNComponentsEnvironment.Production environment prior to this step. Make sure you pass the UNVisaProvider your Visa's App ID, VisaInAppEnvironment.Production and your app's context.

Example:

import com.visa.mobileEnablement.inAppCore.VisaInAppEnvironment
import co.unit.un_components.api.UnitComponentsSdk
import co.unit.un_components.common.models.UNComponentsEnvironment
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        ...
        UnitComponentsSdk.manager.services.setVisaProvider(UNVisaProvider(YOUR_APP_ID, VisaInAppEnvironment.Production, this))
        ...
    }
}

After app development remaining steps

When you are done with the integration, complete the following steps.

Adding a card to Wallet with the Card Component

After completing the instructions to use this capability, set the enablePushProvisioning with the value of true in the Card component additionalSettings parameter. Then, you can add a card to Apple Wallet using the "Manage Apple Wallet" tab in the Card Components's native menu or using an UNCardMenuAction.AddToWallet Incoming event.

val additionalSettings = UNCardViewSettingsBuilder()
    ...
    .enablePushProvisioning(true)
    ...

Add card to wallet as a separate flow

After completing the instructions to use this flow, you can add a card to Google Wallet by calling the Unit SDK's startPushProvisioningFlow(context: Context, cardId: String) method.

Example:

UnitComponentsSdk.manager.ui.flows.startPushProvisioning(context, YOUR_CARD_ID)

IOS SDK

Component name: UNCardComponent

Configuration parameters:

Name	Type	Required	Description
id	String	YES	A Unit card id.
additionalSettings	UNCardViewSettingsProtocol	NO	Advanced optional settings.
callbacks	UNCardComponentCallbacks	NO	Callbacks to interact with the Card component.
theme	String	NO	A URL that specifies the UI configuration.
language	String	NO	A URL that specifies the language configuration.

The callbacks parameter for UNCardComponent is of the following type:

public typealias UNCardComponentCallbacks = (_ callback: UNCardComponentCallback) -> Void

The UNCardComponentCallback is an enum that has the following callbacks that you can receive from a Card component:

public enum UNCardComponentCallback {
    case cardStatusChanged(card: UNCard)
    case cardActivated(card: UNCard)
    case unitOnLoad(result: Result<UNCard, UNComponentsError>)
}

To get the Card Component view, call the getCardComponent method of UnitComponentsSDK.manager.ui.views.

Example:

import UIKit
import UNComponents
import SnapKit

class CardScreen: UIViewController {

    fileprivate lazy var cardComponent: UNCardView = {
        let unViews = UnitComponentsSDK.manager.ui.views
        let cardComponent = unViews.getCardComponent(id: "609414"){ callback in
            switch callback {
            case .cardStatusChanged(let card):
                print("Card status changed \(card)")
            case .cardActivated(let card):
                print("Card activated -> \(card)")
            case .unitOnLoad(let result):
                switch result {
                case .success(let card):
                    print("Successfully loaded card. Card data: \(card)")
                case .failure(let error):
                    print("Failed to load Card component. Error details: \(error)")
                }
            }
        }
        return cardComponent
    }()

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .white

        // add the card component as a subview - using SnapKit for example
        view.addSubview(cardComponent)
        cardComponent.snp.makeConstraints { make in
            make.top.equalTo(view.safeAreaLayoutGuide.snp.top)
            make.leading.trailing.equalToSuperview()
        }
    }
}

Incoming Events:

In some cases, the default menu button won't fit into the design of an application. By using the openActionsMenu() method, it's possible to open the card actions bottom sheet from a custom button.

Important Note: one can use the openActionsMenu() only after UNCardComponent is loaded. (can be verified by onLoad callback)

Example:

cardComponent.openActionsMenu()

It's also possible to create your own menu and call card actions from it. Use openAction(action: UNCardMenuAction) method and send inside an action you want to perform. Use Unit's API Docs in order to understand which actions could be applied.

Example:

cardComponent.open(action: UNCardMenuAction.addToWallet)

You can choose to implement your own show / hide card sensitive data button. In this case use 'showSensitiveData()' method to show sensitive data and 'hideSensitiveData()' method to hide it.

Example:

cardComponent.showSensitiveData()
cardComponent.hideSensitiveData()

The additionalSettings parameter for UNCardComponent is of the following type:

UNCardViewSettingsProtocol:

Name	Type	Default Value	Description
hideActionsMenuButton	Bool	false	Hide the actions menu buttons.
hideCardTitle	Bool	false	Hide the Card title
hideSensitiveDataButton	Bool	false	Hide the Sensitive data ("Show details") button
enablePushProvisioning	Bool	false	Enables Push Provisioning in case value is set to true.
learnMoreUrl	String	""	A “Learn more” URL on the report lost/close card info note.
menuItems	[UNCardComponentMenuItems]		A list of actions, The menu dynamically adjusts based on the provided list `[.freeze, .addToWallet, .managePin, .replace, .report, .close]`.
fee	Double?	null	Base issuing fee for each card (for the "replace card" flow).
showCardTypeSubtitle	Bool	false	Show card type subtitle in case value is 'true'. When enabled, displays the card custom name (if available) in the title.
showCardHolderSubtitle	Bool	false	Show cardholder subtitle in case value is 'true'. When enabled, displays the card custom name (if available) in the title.

You can use UNCardViewSettingsBuilder to create an instance of the protocol and define your additional settings.

Example:

let additionalSettings = UNCardViewSettingsBuilder()
    .hideCardTitle(true)
    .hideSensitiveDataButton(true)
    .enablePushProvisioning(true)
    .menuItems([.freeze])

let unViews = UnitComponentsSDK.manager.ui.views
let cardComponent = unViews.getCardComponent(id: "609414", additionalSettings: additionalSettings)

Add card to wallet

This capability can be used with the Card Component or without it, as a separate flow.

Set Unit SDK with the UNVisaProvider

Call UnitComponentsSDK.manager.services.setVisaProvider with a UNVisaProvider instance. It is recommended to call it inside the application didFinishLaunchingWithOptions method in the AppDelegate.swift file. You will need to make sure you're initializing the manager.environment with UNComponentsEnvironment.Production environment as well. Pass the UNVisaProvider with your Visa's App ID and a VisaInAppEnvironment.Production environment.

Example:

import UIKit
import UNComponents
import VisaInAppModuleCore

@main
class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        let manager: UNComponentsManagerProtocol = UnitComponentsSDK.manager
        manager.services.setVisaProvider(UNVisaProvider(environment: VisaInAppEnvironment.Production, appId: YOUR_APP_ID))

        return true
    }
    ...
}

Adding a card to Apple Wallet with the Card Component

After completing the instructions to use this capability, set the enablePushProvisioning with the value of true in the Card component additionalSettings parameter. Then, you can add a card to Apple Wallet using the "Manage Apple Wallet" tab in the Card Components's native menu or using an UNCardMenuAction.AddToWallet Incoming event.

Add card to Apple Wallet as a separate flow

After completing the instructions to use this flow, you can add a card to Apple Wallet by calling the Unit SDK's func startPushProvisioning(for cardId: String, theme: UNComponentsTheme?, language: UNComponentsLanguage?) method.

Example:

UnitComponentsSDK.manager.ui.flows.startPushProvisioning(for: YOUR_CARD_ID)
