# Security Authorisation Compatability

These limitations apply when electing to set up a security authorisation in PRP

Creating a [security authorisation](/user-guide/selling-and-payment-options/damage-fees-late-fees-non-return-fees.md) using our Security Deposits feature leverages Shopify's card-vaulting capabilities. However, when this is applied to a product in the customer's cart, Shopify restricts some options and features in the checkout. See below for the list of supported and/or unsupported payment gateways, payment methods and sales channels when using our security authorisation / card-vaulting feature.

#### Supported payment gateways

* Shopify Payments
* PayPal Express
* Stripe
* Some Authorize.net configurations
* Adyen on Shopify Plus

#### Supported payment methods

The initial payment must be made using:

* Credit or debit card
* PayPal

Local payment methods and some alternative payment methods are not currently supported by Shopify for this type of checkout.

#### Checkout and sales channel limitations

Security authorisations with card vaulting is only supported through the **Online Store** sales channel.

There is no mechanism to do this via **Shopify POS** or orders created directly in the **Shopify or PRP admin**.

#### Discounts

Standard Shopify discount codes can be used, but in some cases Shopify may apply them differently when a deferred payment is involved. It's best you just try it with your discounting scenario to see the behaviour to ensure it works as expected.

#### Buy now, pay later

**Buy now, pay later** payment options, such as **Afterpay**, cannot be used on orders that include a security authorisation for vaulting card details.

Shopify will automatically disable these methods from checkout when a security authorisation / card vaulting product is detected in the cart.

#### Store credit and gift cards

Shopify Store Credit and gift cards cannot be used to pay for an order when a security authorisation / card vaulting is part of the order.
