Use Card on File with the Square POS App

Use Card on File with the Square Point of Sale app to make selling easy:

  • Securely add and store payment cards from the Square POS app or from your online Square Dashboard by heading to the Customer Directory.

  • Seamlessly charge your customers’ stored payment cards or Square Gift Cards.

  • Safely carry out your business with Square handling PCI compliance and authorisation on your behalf.

Note: You must have written authorisation from your customer to save their payment card. Make sure to keep authorisation forms on file and store them securely to help prevent payment disputes.

Store Payment Cards from the Square POS app

There are three ways to store a card on file with the Square app:

  • From your in-app Customer Directory

  • Before a sale

  • After a sale

From your in-app Customer Directory

  1. Open the Square POS app and tap the three horizontal lines to navigate to the menu.
  2. Tap Customer > select an existing customer from the list or tap the three dots to Create New Customer
  3. Under Card on File, tap Add Card. Note: If you’re creating a new customer, first you’ll need to enter their personal information and tap Save. After the customer is saved in your Directory you’ll see the option to add a Card on File.
  4. Swipe the card with the chip facing downwards, or manually key in the card information, including the CVV and expiry date. You’re required to enter the customer’s full name and email address for receipts. They’ll also receive an email confirming that you have saved a card on file for them. 
  5. Have your customer authorise the card on file for future purchases by entering their billing postcode. 
  6. You’ll see Card Saved once it’s linked to the customer’s profile. Note: If your business has multiple locations, you can use a saved payment card to process a transaction at any location.

When you charge a customer’s card on file, a receipt is automatically sent to the email address associated with their customer profile.

Unlink a Card on File

You can unlink and remove your customers’ cards on file from their profile in your Customer Directory under Edit Personal Information.

Your customers can also remove their own cards by following the link provided to them on all card on file notifications. Customers will receive notifications when their card is stored, when their email address is changed, and when a payment is made using a card on file. The link on these notifications will take them to their Card on File Dashboard, where they can view and remove the cards on file associated with your business.
