What is online credit card processing?

This is a process where credit card transactions take place over the internet and are processed through a merchant service that is able to accept online credit card transactions.

How can I accept credit cards online?

If you want to accept credit cards online for payment, you will need:

  • An e-commerce platform or website to facilitate purchases.
  • A payment gateway to securely accept and encrypt the payment.
  • A merchant account to process these online payments.

What is the cheapest way to process credit cards?

  • Use a merchant service provider as opposed to a bank.
  • Ensure that your payment gateway is PCI compliant.
  • Avoid tiered pricing structures and opt for flat rates instead.
  • Integrate your payments.

How do credit card authorizations work?

When payment is made with a credit or debit card, the merchant contacts the cardholder’s issuing bank and requests an authorization code. The bank’s response to the authorization request will indicate if the merchant can go ahead with the transaction.

Can you legally charge a credit card processing fee?

The practice of charging customers a processing fee for credit card payments is called a surcharge and is currently permissible unless otherwise restricted by state or federal laws.

Paying a surcharge for credit card processing is prohibited in the following states:

  • Colorado.
  • Connecticut.
  • Florida.
  • Kansas.
  • Maine.
  • Massachusetts.
  • New York.
  • Oklahoma.
  • Texas.

How can I accept credit card payments over the phone?

You will need a virtual terminal to process credit card payments over the phone. Payment gateways include virtual terminals as part of their service and include a secure login screen where the customer's information is keyed in and the payment is processed instantly over the internet. The merchant account provider usually pays the funds to your bank account a few days later.

Does credit card processing online always get charged per transaction?

Some online payment services like Helcim charge a flat monthly rate for e-commerce credit card processing, but most charge a small monthly fee in addition to a transaction fee.

Can I also process debit cards online?

Some debit cards can be processed by online merchant services if the debit card has a credit feature, but in most cases, you can only process debit cards in a physical store. An online merchant account works best with credit cards.

Can I set up payment processing on my website, or do I need to redirect customers to an online payment processing site?

With website payment processing, you can integrate an online payment gateway into your online store. This makes website credit card processing much easier for your customers because they can complete their entire transaction on your site.

What are 3rd party credit card processing companies?

A 3rd party credit card company is just a company that performs credit card processing online for small businesses. Since most merchants don't have their own credit card payment solution, they turn to a 3rd party provider.

Can merchant services do more than online credit card processing?

Yes. While some companies only offer online payment processing services, many offer POS systems and other in-store solutions.
