Credit Card Processing Changes 2025 – What Small Businesses Need to Know

Credit card processing in 2025 looks very different compared to just a few years ago. With new interchange fee rules, contactless card processing technology, and PCI DSS v4.0 security standards, small businesses must adapt quickly to stay competitive and compliant. This guide explains the five major changes in credit card processing for 2025 and what they mean for small business payments.

1. Contactless Card Processing Is the Default

The biggest shift in credit card processing 2025 is the dominance of contactless payments:

• Tap-to-pay cards and mobile wallets like Apple Pay and Google Pay are now expected by customers.

• Visa reports over 80% of in-person card transactions are contactless.

Impact:

If your credit card processor or POS hardware isn’t contactless-enabled, you risk losing sales and slowing down checkout.

2. New Interchange Fees and Surcharge Rules

Card networks have updated their credit card processing fees:

• Small ticket discounts now apply to transactions under $5, benefiting quick-service businesses.

• Surcharge rule changes mean stricter disclosure requirements for passing card fees to customers.

Impact:

Merchants must confirm their payment processor supports compliant surcharging or explore dual pricing models.

2025 sees wider adoption of real-time payments (RTP) and instant payouts:

• The FedNow Service has pushed card processors to speed up payouts.

Impact:

This helps small businesses improve cash flow, pay staff faster, and reinvest quickly.

4. PCI DSS v4.0 Security Standards

New PCI DSS v4.0 security compliance rules are now in effect:

• Stronger encryption and authentication are required.

• Tokenization and point-to-point encryption (P2PE) are now standard in modern card processing systems.

Impact:

Businesses need to confirm their credit card processor and hardware meet PCI DSS v4.0 requirements or risk fines.

5. Buy Now, Pay Later (BNPL) Integration

Buy Now, Pay Later (BNPL) is now integrated into many card processing systems:

• Square, Stripe, and PayPal have BNPL options built into checkout.

Adding BNPL can increase average order value and customer conversion but changes transaction fees and accounting workflows.
