Replenish

To ensure security, the Alipay+ NFC SDK payment service requires credentials for each transaction. The SDK requests credentials from Mastercard and stores them locally for further transactions. By default, the SDK stores up to 24 credentials.

The SDK provides the following two methods for replenishing this cache:

• Automatic replenishment: For more information, see Auto-replenish.
• Manual replenishment: For more information, see Manual-replenish.
