Reader SDK Quickstart

Follow this Quickstart to begin taking cash and credit card payments with the Android and iOS Reader SDK sample application:

  1. Get Reader SDK Credentials

  2. Configure the Reader SDK Sample Application

  3. Take a Cash Payment

  4. Customize the Checkout Amount

  5. Take a Credit Card Payment

The Reader SDK lets you take cash payments in addition to credit card payments. This Quickstart begins with cash transactions, which you can do right away, even without deploying the sample application to a physical device.

To take a credit card payment, you must deploy the sample application to a physical device and have a Square Reader available.
