How NMI Payment Processing Works

Payment processing involves securely transferring funds from a customer's payment method (like a credit card) to a merchant's bank account. Several key steps and players are involved in making this happen, and NMI plays a crucial role at multiple points in the process.

Here's a simplified overview of how a typical online payment is processed using NMI:

A customer selects an item on a merchant's website and proceeds to checkout.
At checkout, the customer enters their payment details, which are securely captured by NMI's hosted payment form or the merchant's own form that integrates with NMI's API.
NMI encrypts the payment data and sends it to the payment processor associated with the merchant's account. The processor then communicates with the customer's issuing bank via the appropriate card network (like Visa or Mastercard) to authorize the transaction.
If the transaction is approved, NMI will receive the authorization response and notify the merchant so they can complete the purchase. If it's declined, NMI will display an appropriate error message to the customer.
For approved transactions, the merchant can then submit a capture request through NMI, which triggers the processor to collect the funds from the customer's issuing bank and deposit them into the merchant's designated bank account (usually within 1-3 business days).

Throughout this process, NMI acts as the secure conduit between the merchant, the customer, and the various financial institutions involved. NMI's PCI-compliant infrastructure ensures that sensitive payment data is encrypted and protected at every step.

In addition to securely transmitting transaction data, NMI also provides merchants with tools for managing things like refunds, recurring billing, and account updates to ensure seamless payment experiences. With support for a wide range of payment methods and currencies, NMI allows merchants to easily accept payments from customers around the world.

By streamlining the complex web of connections required for online payment processing, NMI enables merchants to focus on their core business while leaving the intricacies of payment security and compliance to the experts.
