Payment Gateway
When you hear payment gateways, What’s the first thing that comes to your mind? Probably, payment apps like Zelle, PayPal or Stripe.

Spoiler Alert!! You’ve been misinformed. These are not payment gateways, but payment gateway service providers.

It’s a payment processing functionality that allows businesses to accept debit card, credit card or any other pay of payment online. It connects the merchants with their bank’s processing platform and settles the transactions and funds for the merchant.

In Simple terms, it’s an online version of a PoS system that you see in retail stores. The payment gateway encrypts all sensitive information: credit card number, expiration date, and CVV code to protect the users from online frauds and hacks.

Why you need a Merchant Account?

The account is required for the settlement of transactions.

What Are Merchant Account Alternatives?

If you don’t want to go for a merchant account, you can opt for alternatives like Paypal. Paypal Payment Gateway Integration provides a one-stop solution for all the online transactions without any merchant account.
