Merchants targeting Android and desktop users face high abandonment rates when shoppers are forced to manually enter card details on small screens or untrusted devices. The checkout flow requires a mechanism to bypass manual entry, leveraging credentials already stored on the device or browser while maintaining strict security protocols through network tokenisation.
Cardflo enables Google Pay at the checkout, allowing operators to route authenticated network tokens directly to regulated acquirer partners. The platform handles the payload, decrypts the tokenised credentials, and dynamically directs the transaction based on currency, risk profile, and the merchant's active acquirer connections.
Enabling Google Pay through a Cardflo-connected gateway reduces checkout friction and improves conversion rates for mobile transactions. This one-tap payment solution simplifies the purchase journey and tackles issues of drop-off caused by complex payment processes.
Google Pay overview
Deploying a Google Pay integration ensures that merchants can present a one-click payment button to users on compatible Android devices and Chrome browsers. By calling the application programming interface, the merchant checkout requests an encrypted payload containing a network token rather than a primary account number.
Cardflo orchestrates this flow, receiving the encrypted token and passing it through the designated gateway to the most suitable acquirer partner. This process reduces the friction associated with manual card entry and relies on device-level biometrics for authentication.
While managing multiple wallet types requires a broader approach outlined on the digital wallets page, focusing specifically on Google Pay allows operators to capture a massive segment of the Android market. The platform supports automated routing of these tokens across different acquirers, ensuring high approval rates and secure processing without increasing the merchant's compliance burden.
How google Pay works
Google Pay API invocation
The merchant checkout environment detects a compatible Android smartphone or a Chrome browser session and dynamically displays the designated payment button. Upon selection, the application initiates a call to the relevant API, prompting the user to authenticate the transaction using device-level biometrics. The mobile device then generates an encrypted payload containing a secure network token alongside a unique cryptographic cryptogram for authorisation.
Payload decryption and routing
Cardflo receives the encrypted payload directly from the merchant environment. The platform then decrypts the wallet data to extract the network token and associated transaction details securely. The orchestration layer evaluates the specific transaction parameters, including the currency, the merchant classification code, and the current transaction volume, to determine the optimal acquirer partner for processing.
Acquirer partner submission
The system formats the decrypted token into an authorisation request that precisely matches the technical specification of the selected acquirer partner. This regulated acquirer partner then forwards the network token and cryptogram to the issuing bank for final approval. Once the transaction is authorised, Cardflo relays the confirmation back to the merchant checkout, completing the Android web checkout flow rapidly.
Why google Pay matters
Accelerating mobile conversions
Shoppers on mobile devices frequently abandon their carts when faced with lengthy form fields and manual data entry. Presenting a one-click payment option for Android and Chrome users entirely eliminates this manual process, driving significantly higher conversion rates. By relying on stored credentials and device biometric authentication, merchants capture revenue that would otherwise be lost to checkout friction.
Lowering transaction fraud
Transactions authenticated via device biometrics naturally carry a lower risk of fraud compared to standard manual card entry. The deployment of Google wallet payments using network tokens instead of raw card numbers further protects the data flow from interception. This highly secure environment helps reduce chargeback ratios and allows merchants to process high-value transactions safely across the acquirer partner network.
Regulatory notes for google Pay
European authentication mandates
European regulations require strong customer authentication for electronic payments. Transactions initiated through Android devices typically meet these requirements by combining possession of the registered smartphone with inherence via biometric verification.
This dual-factor approach satisfies regulatory demands without requiring an explicit step-up challenge during the checkout process.
Issuing banks retain the final authority to determine if the provided biometric authentication meets their specific risk thresholds. If an issuer rejects the network token's cryptogram, Cardflo can automatically route the transaction through a standard 3D Secure flow.
This fallback mechanism ensures that merchants remain compliant with local directives while preserving the transaction.
Compliance with data security standards
Processing payments via network tokens significantly reduces the compliance scope for the merchant. Because the underlying primary account number is replaced by a secure token, the merchant environment never stores or transmits sensitive card data.
The device generates an encrypted payload that Cardflo decrypts securely on behalf of the operator.
Merchants must still complete the appropriate self-assessment questionnaire to validate their compliance posture. However, leveraging Cardflo to handle the decryption and routing of tokenised payloads limits the merchant's exposure.
The orchestration layer strictly adheres to scheme rules set by Visa and Mastercard regarding the handling and transmission of these encrypted tokens.
Google Pay use cases
Android grocery basket checkout
Grocery applications using the Google Pay API must confirm payment quickly before reserved delivery slots or time-sensitive stock allocations expire. Cardflo routes Google Pay network tokens from Android biometric flows to suitable acquirer partners, while reporting links each authorisation, capture and refund to the merchant’s basket reference.
Android sportsbook account funding
Licensed sportsbook operators accepting Google Pay deposits on Android must apply player limits and gambling controls without delaying pre-event account funding. Cardflo routes the network token to acquirer partners that support the operator’s MCC and market, while transaction references help finance teams reconcile deposits, reversals and withdrawals.
Google Pay event ticket checkouts
Stadium ticket sellers face concentrated Chrome checkout traffic when allocated seats and short-lived reservations are released for major fixtures. Cardflo routes Google Pay network tokens through multi-acquirer routing, helping operators manage authorisation traffic while holding on to order references for later voids, partial captures and event refund reconciliation.
Chrome takeaway order checkout
Takeaway ordering sites serving Chrome users need payment confirmation before kitchens accept short fulfilment windows, while manual card entry can cause baskets to expire. Cardflo supports Google Pay API checkout and routes network-token transactions to appropriate acquirer partners, with reporting that matches authorisations, captures, cancellations and refunds to each order.
Google Pay by the numbers
Typical industry observations suggest that digital wallets can reduce the time spent in the checkout flow by several minutes compared to manual card entry.
Industry reports often indicate a measurable uplift in conversion rates on mobile devices when one-tap payment methods like Google Pay are implemented.
Merchants using network tokens via digital wallets often see a marginal increase in authorisation rates due to reduced friction and better card life-cycle management.

Questions about Google Pay
Which Google Pay API components are required for Chrome checkout integration?
Chrome checkout integration uses the Google Pay JavaScript API to check availability, present the payment sheet and return an encrypted payment data response. The merchant configuration defines supported card networks, authentication methods and the gateway parameters required by Cardflo.
A server-side payment request then passes the returned payload into Cardflo for validation and submission through the appropriate regulated acquirer partner.
How should Android apps pass Google Pay payment data to Cardflo?
An Android app requests payment data through the Google Pay API and receives an encrypted payment method payload after the customer confirms the transaction.
The app should send that payload, the order reference, amount and currency to the merchant’s server rather than attempting to interpret sensitive fields locally. The server submits the request to Cardflo, where it is validated and routed through the configured acquirer partner network.
How do Android biometric checks affect the Google Pay checkout flow?
Google Pay may require the customer to unlock or verify on the Android device before releasing payment data, depending on the device, stored credential and issuer requirements.
That verification occurs within the Google Pay flow, so merchants should not build a separate biometric capture step into the checkout. The resulting payment request can still be subject to additional authentication or issuer checks when required by the transaction context.
What is the difference between Android app and Chrome web checkouts?
The primary difference lies in how the merchant application calls the application programming interface. Native applications use the Google Pay API for Android, which integrates directly with the operating system for instant biometric prompts.
Web-based checkouts utilise the Chrome browser's internal payment request capabilities to access the same stored credentials. Cardflo handles the encrypted payloads from both environments identically, ensuring that the backend routing to the acquirer partner remains consistent regardless of the shopper's device.
