Payment Gateway Testing
A payment gate-way system
is an e-commerce application service that approves credit card
payment for online purchases. Payment gateways safeguard the credit card
details by encrypting sensitive information like credit card numbers, account
holder details and so on. This information is passed safely between the
customer and the merchant and vice versa.
Modern payment gateways
also securely approve payments via debit cards, electronic
bank transfers, cash cards, reward points etc.
Types of Payment Gateway
System
·
Hosted Payment Gateway:
Hosted payment gateway system direct customer away from
e-commerce site to gateway link during payment process. Once the payment is
done, it will bring customer back to e-commerce site. For such type of payment
you don't need merchant id, example of hosted payment gateway are PayPal, Noche
and WorldPay.
·
Shared Payment Gateway:
In shared payment gateway, while processing payment customer is
directed to payment page and stays on the e-commerce site. Once the payment
detail is filled, the payment process proceeds. Since it does not leave the
e-commerce site while processing payment, this mode is easy and more preferable,
example of shared payment gateway is eWay, Stripe.
