To help establish customer trust, you can include a security badge in your theme, and link it to Shopify's documentation on [Payment Card Industry (PCI) standard compliance](https://www.shopify.com/security/pci-compliant?utm_medium=shop&utm_source=secure). Depending on your theme's color scheme, you can use a light-colored, or dark-colored, version. For example: Shopify secure badge Shopify secure badge ## Add security badges to your theme Security badges are often included in the footer or near the **Add to cart** button on product pages. However, they can be included anywhere you have access to include HTML. > Note: > You can't add a security badge to the checkout page unless you're working on a [Shopify Plus](https://www.shopify.com/plus) store that has access to [checkout.liquid](/docs/storefronts/themes/architecture/layouts/checkout-liquid). The following examples show the HTML to include for each version of the badge: ```html Shopify secure badge ``` ```html Shopify secure badge ``` > Tip: > The image files used for each badge are in `.svg` format, so they can be resized with no quality loss.
