Visa Checkout no longer works with Direct Merchants. Merchants will need to reach out to our partners to see if they support Spanish language.
To use Visa Checkout, you must also have a Merchant Service Provider. Visa Checkout does not act as a Payment Gateway, Payment Processor, or Merchant Service Provider: it simply is a digital payment service designed to simplify the checkout experience using a secure, single sign-on across channels and devices using a customer's preferred payment method and works with your existing payment ecosystem.
If you're interested in using Visa Checkout, please reach out to one of our Partners to integrate with Visa Checkout: https://globalcheckout.visa.com/visacheckoutPartners
