Disallow Prepaid Cards

Use the following code snippet in your custom theme’s functions.php file.

add_filter( 'wc_stripe_allow_prepaid_card', '__return_false' );

Hi Roy,

Thanks for the prompt response.

I added that code snippet to my child theme’s functions.php file, but now my entire checkout page is blank cannot seem to access my cart either.

Am I missing anything here? Is this a PHP formatting issue or should I include more code?

P.S. I am PHP illiterate, so I appreciate the hand holding on this.

Make sure you add it after the opening PHP tag <?php

Ok, I found the problem, I had an extra space after the closing php “?>” tag on my functions.php file.

The site is fixed, and I the prepaid card issue should be fixed.

Thanks for your help Roy!

Hi Roy,

After a few days after implementing your solution, I noticed that I am still accepting prepaid debit cards through Stripe.

Why do you think this is still happening and what do I need to do to fix this?

Thanks again for all of your help.

Best,

Marc

Hard to say without seeing your code and how you have everything setup.

I’m happy to send you all of the necessary files or credentials to help get this fixed.

What do you need from me?

Thanks,
Marc

You can start by showing a screenshot of the code you pasted.

Here is the screenshot:

This is what I get on my test site https://cld.wthms.co/79Afns

As a test, put your Stripe settings into test mode by adding in your test API keys in setting and checkout with the credit card number you see in the screenshot and see what you get.

In test mode using the prepaid Mastercard it allowed me to complete my order:

Can you verify that snippet of code is running?

How can I verify that the snippet is running?

You can change it to:

add_filter( 'wc_stripe_allow_prepaid_card', 'marc_allow_prepaid' ); function marc_allow_prepaid( $status ) { error_log( 'prepaid_filtering' ); return false; }

And go through your checkout a couple times in test mode and the prepaid card number, then check your PHP error logs to see if you see the string ‘prepaid_filtering’.

Also what version of Stripe are you using?

So I replaced the code above and tried to checkout with the prepaid MC in test mode a couple of times.

Both times the payment went through, so I went to the error_log file and found this:

I am using WooCommerce Stripe Gateway (Version 3.2.3) and I’m using API version 2017-08-15 in my Stripe Dashboard.
