You already have a card reader on the counter — but did you know it can accept Pix payments directly on the screen, no card swipe needed? Today, SumUp, PagSeguro, Stone, and most card readers on the market display a dynamic Pix QR Code with the exact amount already built in. The fee is lower, the money lands in your account instantly, and the checkout is faster.

In this guide you'll understand how to activate Pix on your card reader, the difference between the reader's dynamic QR and a fixed printed Pix QR at the counter, and when each option makes the most sense for your business.

How Pix QR Code on a Card Reader Works

When you type the amount on the reader and select "Pix," it generates a dynamic QR Code — a unique code for that specific charge, with the amount already embedded. The customer points their phone camera at it, confirms the payment in their banking app, and done: the reader beeps, the screen shows "Payment approved," and the money is already in your account (or available within minutes, depending on the acquirer).

This is different from a fixed Pix QR Code you print out and stick at the counter. The table below summarizes the key differences:

Method QR Type Amount Fee Settlement
Debit card — Typed on reader ~1.5–2 % Next business day
Credit card (lump sum) — Typed on reader ~2.5–3.5 % 30 days
Pix on card reader Dynamic QR Embedded in QR 0–0.99 % Instant
Printed fixed Pix QR Static QR Customer types amount 0 % Instant

The fixed (static) Pix QR costs nothing but requires the customer to type the amount — leaving room for errors. The reader's dynamic QR already contains the correct amount, reducing mistakes and speeding up checkout.

How to Activate Pix on Your Card Reader

The exact steps vary by brand, but the general flow is:

  1. Open your acquirer's app (SumUp, PagSeguro, Stone, Cielo, Rede, Getnet, Ton, etc.) on your phone.
  2. Go to Settings → Payment methods.
  3. Enable Pix and link a Pix key to your account.
  4. Done — on your next charge, "Pix" will appear as a payment option on the reader's screen.

Some older readers need a firmware update. If the Pix option doesn't show up, update the reader's software through the app or contact your acquirer's support team.

Step-by-Step: Charging with Pix QR on the Card Reader

  1. Enter the amount on the card reader.
  2. Select "Pix" as the payment method.
  3. The screen displays a dynamic QR Code with the amount.
  4. The customer points their phone camera and scans it.
  5. They confirm the payment in their banking app.
  6. The reader shows "Payment approved" — usually within 10 seconds.
  7. Print the receipt on the reader or through the app.

No PIN, no tap, no card insertion. The process is as fast as debit — and cheaper.

Card Reader vs Printed Fixed Pix QR: When to Use Each

The card reader with Pix is ideal when:

  • The sale amount varies (restaurant, retail, services with variable ticket).
  • You want an automatic receipt generated by the reader.
  • You prefer to centralize all income in one account.

A fixed printed Pix QR at the counter makes sense when:

  • You have a product or service with a fixed price (e.g., coffee for R$ 5.00 / $1.00).
  • You want a backup in case the reader runs out of battery or loses internet.
  • You serve fast queues where the customer already knows the amount and types it themselves.
  • You want zero cost — no reader rental fee, no transaction fee.

These two methods complement each other. Many small businesses use the card reader as the primary method and keep a fixed Pix QR taped to the counter as a fallback. To learn more about how Pix QR Codes work, see how Pix works with QR Code.

Common Mistakes

❌ Not activating Pix before trying to charge

The Pix option doesn't appear automatically on every reader. You must enable it in the acquirer's app settings and link a Pix key.

❌ Pix key tied to a different account

The Pix key must belong to the same tax ID linked to the acquirer account. Using a personal key on a different account can cause errors or delayed settlement.

❌ Showing the QR before the customer confirms the amount

In noisy or rushed environments, customers may scan the QR before checking the amount on the screen. Always say the amount out loud or turn the screen toward the customer before generating the QR.

❌ Confusing dynamic QR with static QR

The QR generated by the card reader expires after payment (or after a few minutes). You can't reuse the same QR for different charges. For a reusable QR, use a fixed Pix QR — see parking and fixed billing.

❌ Relying solely on the card reader with no backup

A dead battery or no internet connection means a lost sale. A printed fixed Pix QR at the counter solves this in seconds.

Summary

  1. Modern card readers (SumUp, PagSeguro, Stone, etc.) support dynamic Pix QR — activate it in the app settings.
  2. The Pix fee on the reader (0–0.99 %) is lower than debit and far lower than credit.
  3. Money settles instantly, no waiting for business days.
  4. Use the reader when amounts vary; use a fixed printed Pix QR when the price is fixed or as a backup.
  5. Code2Scan generates a free fixed Pix QR — perfect to stick at the counter so you never miss a sale.
