Card Present Overview


The Card Present solution is currently in Beta.


Card Present refers to transactions for merchants based in the US where the payer and merchant are face to face and begin a transaction with a physical card present. Our Card Present solutions require permission from WePay to integrate, so be sure to get in touch with your account manager and/or integration team.

If you do not already have an account manager and/or integration team, reach out to us to start this process:

Integration Effort

You'll need the following items, which your integration team at WePay will guide you through acquiring:

  • Pre-Certified devices
  • Card Present SDK
  • API extensions

Your integration will vary depending on the type of Pre-Certified devices that you order. We offer two types of Pre-Certified devices:

  • Terminals -- These are stand-alone devices which handle card authorization. They have their own network capabilities and UIs.
  • Mobile Card Readers -- These devices read card data, and rely on network capabilities and UIs from the connected mobile device an application in order to process authorizations.

Integrate The Card Present SDK

The Card Present SDK converts authorization data and metadata collected by a Pre-Certified device into an encoded payment method token used to create a Payment via the API.

Due to the permissioned nature of Card Present transactions, reach out to your account manager to receive the Card Present SDK package.

To install, configure, and initialize the Card Present SDK, follow the PDF Getting Started integration guide provided in the SDK package. The Getting Started guide is also available on the home page of the static HTML site provided in the SDK package.
