QR Code Payment: How It Works (2026 Complete Guide)

QR code payments work by encoding payment information in a scannable code. Customers scan with their phone camera or payment app to complete transactions. Major platforms include Venmo, Cash App, PayPal, Apple Pay, and Square. For businesses, QR payments reduce hardware costs and speed up transactions—especially valuable for small vendors, restaurants, and service providers.

How QR Code Payments Work

There are two main types of QR code payments:

### Customer-Presented QR

The customer displays a QR code from their payment app. The merchant scans this code to charge the customer's account. Common with Apple Pay, Google Pay, and retail store apps.

### Merchant-Presented QR

The merchant displays a QR code (printed or on screen). The customer scans this to initiate payment. Popular with Venmo, Cash App, PayPal, and small businesses.

Major QR Payment Platforms

Venmo's QR codes let customers pay directly from their Venmo balance, linked bank account, or card.

Frequently Asked Questions

How do I accept QR code payments at my business?

The easiest way is to create a business account on Venmo, Cash App, or PayPal and display their generated QR code. For integrated solutions, use Square or Stripe which connect QR payments to your POS system.

Are QR code payments secure?

Yes, when using legitimate payment platforms. The QR code itself just initiates the transaction—actual payment processing happens through encrypted banking systems. Risks come from fake QR codes, so merchants should secure their displayed codes.

What are the fees for QR code payments?

Fees vary by platform: Venmo Business charges 1.9% + $0.10, Cash App charges 2.75%, Square charges 2.6% + $0.10. These are typically lower than traditional card terminal fees, especially for small transactions.

Can I create a custom QR code for payments?

Payment QR codes must be generated by your payment provider (Venmo, PayPal, Square, etc.) to work correctly. However, you can create custom QR codes linking to payment pages—but the actual payment processing still needs a legitimate platform.
