=== Two different goals: (A) testing a web checkout that accepts Google Pay, and (B) using your provisioned virtual card in Google Wallet at physical POS (contactless). ===

===== 1. Merchant provides sandbox/staging checkout (or you create a staging checkout using the same gateway). =====
# Use the Google Pay web client code above (environment: 'TEST') and gateway test keys (Stripe test keys).
# Ensure your server is using Stripe test secret key to confirm PaymentIntent.
# Use Google Pay test cards (from Google docs) when in TEST mode.
# Confirm the PaymentIntent in Stripe Dashboard (test mode) and verify merchant receives simulated settlement in their sandbox.

===== Important: You can only tap & pay at a real POS terminal if: =====
* The card is provisioned (tokenized) to Google Wallet by an Issuer (Stripe Issuing / Marqeta etc).
* The provisioning includes network tokens that the POS accepts (Visa/MC tokens).
* The POS terminal supports contactless and the terminal/acquirer accepts that token.

Steps:
# Provision a virtual card to Google Wallet as described earlier.
# Add the card to your Google Wallet on a test device (phone) using the issuing provider’s provisioning flow.
# Configure the card spending limits and funding source in the issuer console.
# Visit a contactless POS (store) that accepts contactless Visa/Mastercard. Tap to pay with Google Wallet.
# Check the merchant’s till to ensure it shows an authorization and then settlement (in their sandbox if possible).
# Reconcile the transaction in the issuer’s portal / Stripe Issuing test dashboard.

If you can’t provision a card yourself, ask the merchant to accept Google Pay tokens produced during a test (merchant sandbox). Many merchants use Stripe/Adyen so testing their gateway sandbox is effective.
