Taking orders online can mean big cost savings for your business or organisation.

You can take payments through your @UK site by cheque or account as standard, but in order to take online credit and debit card payments through your @UK website you require two things:

1. Internet Merchant Account

An IMA can be set up with a bank or Internet company and is an agreement to allow a business to accept credit / debit card payments. This type of account is separate from your normal business account.

2. Payment Service Provider

A PSP or payment gateway is a service which ensures customer credit / debit card details are passed securely from your website to the bank (or company) where your IMA is held. From here, the PSP then passes these details to the card holder’s bank to authorise payment. PSP services are offered by both banks and internet companies.

Both these services are offered by both banks and internet companies.

The Payment Process

Understanding the online payment process can be confusing. Below is a simple diagram of how an @UK website accepts credit and debit card payments, once an IMA and a payment gateway has been set up.

  The Payment Process

Step 1 - Customers go to your @UK website, select the products and services they would like to purchase and enter their credit or debit card details.

Step 2 - Your @UK website securely captures these details and is collected by a PSP.

Step 3 - The PSP then passes the card details to the bank where your IMA is held. From here, the PSP then passes these details to the card holders bank to authorise payment.

Step 4 - The payment is deposited into your Internet Merchant Account.
