Accessible credit card processor apps

Hello,
I am thinking of starting my own business for technology support for the blind, and was wondering if anyone has any tips for accessible apps for credit/debit card payments. I am not sure when I am going to start my business, but it might be soon. Any suggestions?

#1 Paypal?

If you want to use Paypal, accessibility is possible on the web and in apps, particularly with embedding Paypal buttons. Obviously you should be aware that you will likely need to set up a Paypal Business account to gain support for business-related tasks in relation to embedding Paypal buttons into your website, however both personal and business accounts can send invoices. Do you already have a website created for your business in which a potential Paypal button could be added?

I use square for all of my credit car stuff. I don't think you can embed but it works for what I need it to do.
