If you are only using us with PayPal Payments Standard, buyers will only see a PayPal checkout button in their shopping cart; however, the PayPal Standard checkout site can usually offer a card-based payment option for buyers who don't have a PayPal account.
First make sure you have taken the free upgrade to a PayPal Business or Premier account that is PayPal Verified, and in your PayPal account under [your name] > Account Settings > Website Payments > Website Preferences, make sure you have set PayPal Account Optional: ON.
Once you have that set up, when a buyer clicks the PayPal checkout button in your cart, the PayPal checkout site should offer buyers the choice to either Log Into PayPal or Pay With a Credit or Debit Card.
Note that buyers cannot pay with a card that is already linked to a PayPal account; instead, they would need to log into that PayPal account to fund their payment from that linked card. The PayPal checkout site also will not offer the card payment option if you are using us with PayPal Payments Pro, or if the buyer is located in a country where PayPal doesn't support card payment without a PayPal account.
If you want your E-junkie shopping cart to show a separate checkout button for card payments, you will need to add one of the other payment services we support listed here. In this case, buyers who wish to pay with a card would simply click the dedicated Pay With Card checkout button we'd show in your E-junkie cart, rather than clicking the PayPal checkout button there.
