Best Online Payment Systems: Payment Processors and Payment Gateways
Best Online Payment Systems: Payment Processors, Payment Gateways

In this article, we’ll be reviewing the best online payment systems, payment processors and payment gateways for accepting e-commerce payments on the Internet.
Online Payment Systems Primer
Before getting started, here are just a few things to know about online payment systems.
Automated Clearing House (ACH)
ACH is an electronic network for financial transactions in the United States. ACH processes electronic credit and debit transactions, allowing customers to make payments from their bank accounts for utilities, mortgage loans, and other kinds of bills. Most payment processors offer ACH payment options to their customers, especially for monthly and subscription-based transactions.
Merchant Account
A merchant account is a type of bank account that allows businesses to accept payments by payment cards, typically debit or credit cards. Merchants are contractually bound to obey the operating regulations established by the card associations. Many processors such as Sage Pay and PayPal act as both the merchant account and payment gateway.
Payment Gateway
A payment gateway is an e-commerce application service provider service that authorizes credit card payments for e-businesses and online retailers. It is the equivalent of a physical point of sale terminal located in most retail outlets. The payment gateway allows secure credit card transactions between the customer and the merchant and between the merchant and the payment processor.
Payment Processor
A payment processor is the company designated by a merchant to handle credit card transactions. Payment processors implement anti-fraud measures via card associations and issuing banks to ensure the customer and merchant are protected.
Payment Card Industry (PCI) Compliance
PCI compliance is adherence to a set of specific security standards that were developed to protect card information during and after a financial transaction. PCI compliance is required by all card brands. For PCI compliance the vendor must:
- Build and maintain a secure network.
- Protect cardholder data.
- Maintain a vulnerability management program.
- Implement strong access control measures.
- Regularly monitor and test networks.
- Maintain an information security policy.
Some payment processors such as Sage Pay offer simplified PCI compliance requirements depending on the integration method you’ve chosen. This makes it cheaper and quicker for you to become compliant.

PayPal
PayPal allows any business or individual with an email address to securely, conveniently and cost-effectively send and receive payments online. PayPal’s network builds on the existing financial infrastructure of bank accounts and credit cards to create a global, real-time payment solution. PayPal delivers a product ideally suited for small businesses, online merchants, individuals and others currently underserved by traditional payment mechanisms. The size of PayPal’s network and widening acceptance of their product have helped them become one of the leading payment networks for online auction websites, including eBay. PayPal is also being increasingly used on other ecommerce sites for the sale of goods such as electronics and household items, the sale of services such as web design and travel, and the sale of digital content. Offline businesses, including lawyers, contractors and doctors, have increasingly begun to receive payments online through PayPal. PayPal’s service, which lets users send payments for free, can be used from computers or web-enabled mobile phones. PayPal UK Pricing
