A payment processor is a company that facilitates credit and debit card transactions by connecting merchants to card networks (Visa, Mastercard), acquiring banks, and issuing banks. They provide the technical infrastructure that makes card acceptance possible.
The payment processor handles: - Transaction routing (sending authorization requests through the correct network) - Security (encryption, tokenization, fraud detection) - Settlement (batching and transferring funds) - Reporting (providing statements and transaction data) - Dispute management (handling chargebacks and retrievals)
There are two models: 1. **Processor-direct**: The merchant contracts directly with a large processing company (TSYS, First Data/Fiserv, Global Payments, Worldpay). Often requires volume minimums. 2. **Through an ISO**: Independent Sales Organizations (ISOs) like Liberty Bancard resell processing services from larger processors under their own pricing structures. ISOs provide personalized service and can often negotiate better rates for their merchants.
Major payment processors include: Fiserv (formerly First Data), Global Payments, TSYS (now part of Global), Worldpay (FIS), Chase Merchant Services, and Stripe.
Processors earn money on the markup portion of interchange plus pricing — the difference between what the card network charges and what the merchant pays.
Choosing the right payment processor affects your rates, service quality, and account stability. Questions to ask any processor: What is your exact markup over interchange? What are all monthly fees? What is your chargeback support process? What is your next-day funding policy? What equipment do you support?
Don't focus only on the per-transaction rate — evaluate the full relationship including support quality, contract terms, and cancellation fees.
When a customer swipes their Visa card at a restaurant: 1. Restaurant terminal sends transaction to Liberty Bancard (ISO/processor) 2. Liberty Bancard forwards to their acquiring bank partner 3. Acquiring bank routes to Visa network 4. Visa routes to customer's issuing bank (Chase, BoA, etc.) 5. Issuing bank approves → response travels back through chain in under 2 seconds 6. Transaction approved; restaurant gets paid at settlement
A payment processor handles the financial transaction and moves money between parties. A payment gateway is the technology interface that connects your website or terminal to the processor. Many processors include a gateway; some are separate services.
Compare effective rates (not just quoted rates), contract terms, monthly fees, chargeback support, equipment compatibility, and customer service. Get quotes from 2-3 processors and ask each to review your actual processing statements.
