Take Payments on Square Hardware

Use Square's in-person payment solutions to process payments and build integrations with the seller's POS application. Depending on the seller's use case, you can integrate your in-person payment solutions with Square Terminal, Square Reader, or Square Stand. Along with Square hardware, use the Terminal API, Reader SDK, or Point of Sale API to enable your POS application to process and manage payments and perform other buyer-facing actions.

Take payments with the Terminal API and Square Terminal
The Terminal API lets your POS application collect payments using Square Terminal. Because the Terminal API is a cloud-based API, you can access it from any third-party POS application connected to the Internet. The Terminal API also supports device management, device customization, and buyer-facing features such as saving a card on file and signature capture.

Take payments with the Reader SDK and Square Reader or Square Stand
The Reader SDK provides an embedded Square checkout flow and accepts in-person payments in a custom Android or iOS application using a Square Reader Contactless Chip or Magstripe or Square Stand. This simplifies chip and NFC payments, addresses EMV certification requirements, and makes PCI compliance easy. The SDK supports authorization, payment processing, and Reader management.

If the Reader SDK isn't available in your region, use the Point of Sale API to switch seamlessly to the Square Point of Sale application and collect payment with Square Readers. The Point of Sale API is available for native and web applications on iOS and Android.

After reviewing an in-person payment integration, compare it against each solution's key features that best suit your seller's business.

Did you know?

If sellers enable their account to accept in-person Afterpay payments, they can accept Afterpay payments using Terminal API, Reader SDK, or Point of Sale API with no additional development effort. Buyers with Afterpay accounts can pay with their Afterpay Card using the Google Pay or Apple Pay NFC payment methods on the Square Terminal, Square Reader, or Square Stand. For more information about how sellers can activate Afterpay for in-person payments, see Accept In-Person Payments with Afterpay and Square.
