How to Accept Credit Cards
Accepting credit cards means enabling customers to pay with a card issued by a bank or network such as Visa, Mastercard, American Express, or Discover. Businesses do this through a combination of hardware, software, and a payment processor that moves money from the customer's bank to the merchant's account. The right setup depends on where you sell, how customers pay, and how much you are willing to spend on fees and equipment. This guide covers the main ways to accept credit cards, what things cost, and how to choose a setup that fits your business.

Ways to Accept Credit Cards
In-Store and Point-of-Sale Terminals
Physical stores typically use a card terminal or point-of-sale system that reads the chip, magnetic stripe, or contactless chip inside a card. The terminal connects to a payment processor over the internet or a phone line, verifies the transaction, and returns an approval or decline in seconds. Many modern terminals also accept mobile wallet payments such as Apple Pay and Google Pay, which use tokenized card data for extra security. For businesses that process a high volume of in-person transactions, a dedicated POS terminal usually offers lower per-transaction fees than online-only options.
Online and Mobile Payments
Online stores rely on a payment gateway connected to a merchant account. The gateway encrypts card details entered on a checkout page and sends them to the processor for authorization. Popular options include hosted checkout pages, API-integrated payment forms, and payment links that can be sent by text or email. Mobile card readers, such as those that plug into a smartphone or tablet, let field service workers, pop-up vendors, and delivery drivers accept credit cards anywhere with a data connection. Each of these methods has a different fee structure and setup complexity.
Invoicing and Manual Entry
Some businesses accept credit cards by sending an invoice with a payment link or by manually keying card details into a virtual terminal. This is common for service providers, consultants, and subscription businesses where the customer is not physically present. Manual entry typically carries higher fees because the transaction is classified as card-not-present, which carries more fraud risk for the processor.
What It Costs to Accept Credit Cards
Credit card processing involves several layers of fees, and the exact numbers vary by processor, sales channel, and transaction volume. Understanding these costs helps you compare options without being surprised by hidden charges.
| Fee Type | Typical Range | Context |
|---|---|---|
| Discount Rate | 1.5% – 3.5% per transaction | Covers interchange and network fees; varies by card type and sales channel |
| Per-Transaction Fee | $0.10 – $0.30 | Flat fee added on top of the percentage |
| Monthly or Annual Fee | $0 – $50+ | Some processors charge for the account, terminal rental, or software |
| Chargeback Fee | $15 – $50 per dispute | Applied when a customer disputes a transaction and the processor investigates |
| Equipment Rental | $15 – $50/month | Common for countertop terminals; some providers let you buy the hardware |
Interchange fees, set by the card networks and issuing banks, make up the largest portion of processing costs. These rates are not negotiable, but processors can differ in their markup, so comparing the total effective rate is essential.
How to Set Up Credit Card Acceptance
The setup path depends on the sales channel. For in-store acceptance, you typically choose a processor, select a terminal or POS system, and sign up for a merchant account. Many providers bundle the merchant account with the processor, so you do not need to apply for one separately. For online businesses, you integrate a payment gateway into your checkout flow, configure your payment methods, and test transactions in sandbox mode before going live. Mobile setups usually require a card reader that connects via Bluetooth or a headphone jack, plus a compatible app on your phone or tablet.
Security and Compliance
Any business that accepts credit cards must follow the Payment Card Industry Data Security Standard, known as PCI DSS. This set of rules governs how cardholder data is stored, transmitted, and processed. Most small businesses use a payment gateway or terminal that handles the sensitive data on their behalf, which simplifies compliance. You should still use secure networks, keep software updated, and avoid storing full card numbers unless you have a legitimate, secured reason to do so.
Choosing the Right Processor
When comparing providers, look beyond the headline discount rate. Consider contract terms, early termination fees, settlement speed, customer support availability, and whether the processor supports the sales channels you use today and might use tomorrow. A processor that works well for a simple online store may not be the best fit for a business that also needs in-person terminals or recurring billing tools.
