# Payment Method Service Overview

## Overview

The Payment Method Service enables you to securely store payment methods at payment processors using the Java SDK. Tokenization replaces sensitive card data with secure tokens, enabling one-click payments and recurring billing without PCI compliance exposure.

**Business Use Cases:**

* **One-click checkout** - Returning customers pay without re-entering card details
* **Subscription billing** - Stored payment methods for recurring charges
* **Vault migration** - Move existing tokens between processors
* **PCI compliance** - Reduce compliance scope by avoiding raw card storage
