Credit card logos
They signify to users the payment options that are available. Showing them in the footer is a good way to reassure your customers. There are very few things more annoying than spending your time on a site only to discover that it doesn’t accept your payment method when you try checking out.
You should also make those credit card logos big enough so they’re easily visible. It’s also important to display those logos exactly as the parent companies display them, in full color. No black and white logos or plain text links. Displaying incorrect logos only makes you come across as some clown bungling a phishing operation.
If you accept multiple payment methods, let’s say more than five, there is no point in displaying them all. It just clutters the design and comes across as tacky. You should display the most commonly used ones and hide the rest.
Trust and safety badges
These badges confer a lot of credibility that you will need as an up and coming store. The rise in cybercrime has put everyone on guard. A full 17% of people surveyed by Baymard abandoned their carts at checkout because they didn’t trust the e-commerce stores in question with their credit card information.
You can also add a guarantee badge, such as a 100% satisfaction guarantee.
Typically, these logos appear on the right side of the footer. If you also have a section with those logos on the homepage, you can omit them on the homepage footer or from your footer altogether.
Most sites that have logos and badges put them in the footer or right above the footer.
