This is an eCommerce payment method for the Stripe payment gateway.
This payment method handles credit card payments using an attractive and modern credit card form. With Stripe you don't need a merchant account or gateway, and they can make direct payouts to your bank account.
Stripe uses a token based method of making transactions, meaning that your web site never directly handles credit card data (removing PCI concerns).
