# Use the Sample Apps (/archive/paypal-here/using-sample-apps)



> **Note:** **Important:** PayPal Here is [deprecated](https://www.paypal.com/us/cshelp/article/paypal-here-deprecation-help299). PayPal doesn't accept new integrations but continues to support existing integrations.

To become familiar with the SDK, review our platform-specific sample apps:

* iOS
* Android
* Web

To get started with the sample apps:

1. Have a sandbox or production PayPal account with PayPal Here enabled.
2. Have your EMV reader already paired, via bluetooth, to your device.

> **Note:** **Note:** Step 2 is only required if you use the
> [Chip Card Reader](https://www.paypal.com/us/business/pos/payments/card-reader).
> The
> [Chip and Tap](https://www.paypal.com/us/webapps/mpp/credit-card-reader-how-to/chip-and-tap-reader)
> and
> [Chip and Swipe](https://www.paypal.com/us/business/pos/payments/card-reader)
> readers can connect without pairing them to your device beforehand. Also note
> that for the Web SDK, you simply need to have your pre-configured
> [Chip Card Reader](https://www.paypal.com/us/business/pos/payments/card-reader)
> plugged in via USB.
