The Alipay+ NFC SDK provides APIs for implementing Alipay+ NFC payment functionality in your applications. The following table lists the available functions.

Phase	Function	Description
Initialization	`IAPApplePay.setConfiguration(config:)`	Initialize the SDK and set overall configurations.
	`IAPApplePay.connect(params:)`	Switch the current operation context to the specified user account. Call this after user login or account switch.
	`IAPApplePay.disconnect()`	Disconnect the current user and clear sensitive context from memory. Call this after user logout.
	`IAPApplePay.destroy()`	Deinitialize the SDK, release memory resources, and terminate background tasks.
Proxy Settings	`IAPApplePay.setNetworkProxy(_:)`	Set up a network proxy for communication between the SDK and the Alipay+ Server.
	`IAPApplePay.setLoggerProxy(_:)`	Set up a logger proxy for log output.
	`IAPApplePay.setTrackingProxy(_:)`	Set up a proxy for event tracking.
	`IAPApplePay.setRemoteConfigProxy(_:)`	Set up a proxy for managing SDK configurations remotely.
Static Token	`IAPApplePay.createStaticToken(completion:)`	Create a static token for the current user.
	`IAPApplePay.getStaticTokenInfo(completion:)`	Retrieve information about the current user's static token.
	`IAPApplePay.getStaticTokenVerificationInfo(completion:)`	Retrieve static token verification information.
Service Management	`IAPApplePay.suspendService(completion:)`	Pause all services and suspend all tokens, including those added to Apple Wallet.
	`IAPApplePay.unsuspendService(completion:)`	Resume all services and tokens, including those added to Apple Wallet.
	`IAPApplePay.getServiceState(completion:)`	Get the current service state for the user.
Apple Wallet and Device Token	`IAPApplePay.addToAppleWallet(completion:)`	Create a device token for the current device or paired device and add the token to Apple Wallet.
	`IAPApplePay.canAddToCurrentDevice(completion:)`	Check whether the current device is capable of adding the token.
	`IAPApplePay.canAddToPairedDevice(completion:)`	Check whether the paired device, for example, an Apple Watch, is capable of adding the token.
	`IAPApplePay.presentCurrentDeviceToken(completion:)`	Present the device tokens already provisioned for the current user on the current device.
	`IAPApplePay.getDeviceTokenOnCurrentDevice(completion:)`	Retrieve the device token of the current device.
	`IAPApplePay.getDeviceTokenOnPairedDevice(completion:)`	Retrieve the device token on the paired Apple Watch.
In-App Verification	`IAPApplePay.activateDeviceToken(deviceAccountIdentifier:redirectUrlStr:completion:)`	Activate a device token. Perform user authentication before calling this method.
Wallet Extension	`IAPApplePay.statusForPassEntries(completion:)`	Report the status of your Wallet Extensions.
	`IAPApplePay.availablePassEntries(completion:)`	Report the list of device tokens available to add to the current device.
	`IAPApplePay.availableRemotePassEntries(completion:)`	Report the list of device tokens available to add to the current paired device.
	`IAPApplePay.generateAddPaymentPassRequestForPassEntryWithIdentifier(_:configuration:certificates:nonce:nonceSignature:completion:)`	Create the data object required by Apple to add a card to ApplePay

Note: If your project integrates this SDK using Objective-C code, you need to use the IAPApplePayBridge class instead of the IAPApplePay class, to ensure full compatibility. IAPApplePayBridge is a bridging class specifically optimized for Objective-C code and is used in the same way as IAPApplePay.
