Requires an active CARDZ3N merchant and payment gateway account. Contact us to get set up.

The plugin itself is free; you only need an active CARDZ3N merchant account to process live payments. Because checkout stays embedded on your own store, customers never leave your site to pay, which keeps the buying experience consistent and helps reduce abandoned carts. The same gateway handles one-time orders, WooCommerce Subscriptions renewals and pre-orders, so you can manage cards, ACH and digital wallets from a single dashboard instead of juggling separate processors. If your store sells in a higher-risk category, our team can review your products and approval options before you install.

CARDZ3N is a Las Vegas-based merchant services provider for businesses that traditional processors turn away, offering high-risk merchant accounts, gateway and POS integrations, ACH processing and chargeback prevention for merchants in the USA, Canada, the UK and the EU.
