# Prerequisites

This section outlines the prerequisites to start the integration process with the
Google Wallet open loop payment method:

- Transit terminals or card readers need to support Europay Mastercard Visa (EMV) credit and debit payments. L1 and L2 EMVCo certification is required. For more information about EMV certification, see [Product Approval/Evaluation Processes](https://www.emvco.com/processes-forms/product-approval/).
- Users must have a mobile device with Android 9 (Pie) or later that supports near field communications (NFC) and host card emulation (HCE).
- Google Wallet needs to be live in the country where the transit agency resides. To find links to live countries, see [Countries where you can use Google Wallet](https://support.google.com/pay/answer/9023773).

If you meet all the prerequisites, do the following:
