What is a Payment Processor?
A payment processor is a company that handles the technical infrastructure for processing card payments. It routes transaction data between the merchant, the acquiring bank, the card network, and the issuing bank, managing authorisation, clearing, and settlement.
How Payment Processors Work
When a customer taps, inserts, or enters their card details, the payment processor takes over. It encrypts the transaction data, routes it through the appropriate card network to the issuing bank for authorisation, and returns the approval or decline to the merchant — all within seconds.
After authorisation, the processor handles clearing (exchanging transaction details between banks) and settlement (transferring funds to the merchant).
Types of Payment Processors
Front-End Processors
These handle the authorisation side — connecting merchants to card networks and processing approval requests in real time.
Back-End Processors
These handle settlement — ensuring funds move from the issuing bank through the card network to the acquiring bank and into the merchant's account.
Full-Stack Processors
Many modern processors handle both front-end and back-end processing, offering merchants a single point of integration.
Payment Processors vs Payment Gateways
A payment gateway is the interface that captures card details (online checkout page, virtual terminal, or phone payment system). The payment processor is the engine behind it that routes and processes the transaction. Many companies offer both services together.
Paytia works with all major payment processors. When a customer makes a phone payment through Paytia's secure payment platform, the card data is captured by Paytia and sent to the merchant's chosen payment processor for authorisation and settlement. Paytia is processor-agnostic — it integrates with Stripe, Worldpay, Barclaycard, Adyen, and many others.
Frequently Asked Questions
What is the difference between a payment processor and a payment gateway?
A payment gateway captures and encrypts card details at the point of sale (online, in-store, or over the phone). A payment processor routes those details through the card network for authorisation and handles settlement. Many companies offer both services.
How do payment processors make money?
Payment processors charge merchants per-transaction fees (a percentage plus a fixed amount), monthly fees, and sometimes setup fees. Rates vary based on transaction volume, average transaction size, and the merchant's risk profile.
Can I switch payment processors?
Yes. Merchants can switch processors, though there may be contract termination fees. The switch typically involves integrating with the new processor's API or gateway. Paytia's processor-agnostic platform makes switching easier as only the gateway connection needs to change.
