Tokenization & Saved Cards

Updated on November 27, 2025

Tokenization allows customers to save their card details for faster checkout on future purchases. Card data is securely stored by PowerTranz – sensitive information never touches your server.

How Tokenization Works

When a customer saves their card:

  1. Card details are sent securely to PowerTranz
  2. PowerTranz stores the card and returns a token (a unique identifier)
  3. The token is saved in WooCommerce, linked to the customer’s account
  4. For future purchases, only the token is used – no card details are transmitted

Enabling Tokenization

To enable saved cards:

  1. Go to WooCommerce → Settings → Payments → PowerTranz
  2. Check the Enable Tokenization option (“Payment Settings” Tab)
  3. Save changes

Tokenization is enabled by default.

Customer Experience

Saving a Card

During checkout, logged-in customers will see a checkbox option to save their card for future purchases. Guest customers cannot save cards.

Using a Saved Card

On future checkouts, customers can select from their saved cards instead of entering card details again.

Managing Saved Cards

Customers can manage their saved cards from their account:

  1. Go to My Account → Payment Methods
  2. View all saved cards
  3. Delete cards they no longer want saved
  4. Set a default payment method

Subscriptions & Saved Cards

Tokenization is required for WooCommerce Subscriptions. When a customer purchases a subscription, their card is automatically saved to enable automatic renewal payments.

Customers can update the card used for their subscription from:

  • My Account → Subscriptions – Change payment method for a specific subscription
  • My Account → Payment Methods – Manage all saved cards

Security

  • Full card numbers are never stored on your server
  • Only the last 4 digits and card type are saved for display purposes
  • Tokens are unique to your merchant account and cannot be used elsewhere
  • 3D Secure can still be applied to saved card transactions for additional security
