Redirects In a redirect payment gateway, the customer is driven to the PayPal payment page to complete the transaction. It is particularly a good option for small businesses. They get to benefit from the convenience and security offered by a platform like PayPal.
On-Site Checkout, Off-Site Payment For example- Stripe. The checkout will happen on the website itself but the payment will occur at Stripe’s back end. This also is a simple payment gateway option but like redirects offers some restrictions on your control over the user’s experience. Katie Keith also supports this idea.
On-site Payments This is a popular idea amongst the larger businesses. As the word implies, they handle the entire payment process on their servers themselves, hence exercise more control over the same. Also, let us not forget to mention here that with great control comes responsibility too.
