Outlines the options for connecting to networks, and how processing payments works where there is no network connection.
To ensure the highest authorization and conversion rates, it is always best to process payments online. However, sometimes networks are unavailable for a variety of reasons. To prevent loss of service, Adyen provides the following solutions:
- 3G / 4G router
- Terminal with intelligent failover to 3G/4G.
- Offline processing
- MOTO payments via Adyen's First Line support.
Your own router with 3G or 4G network failover functionality, preferably with external antennas for optimal reception. Benefit of this approach is a greatly reduced service interruption when the main internet connection fails (e.g. ADSL, cable or fiber), resulting in almost no degradation of payment service (online authorization, PIN online, reconciliation, all cards). Adyen sees Merchants with almost 100% uptime with this solution.
This service comes with an extra fee per terminal per month.
Payment Terminal with intelligent failover (including to 3G/4G cellular).
- Available terminals: The VX690 and V400m are shipped with a sim card inserted, and can be activated remotely by Adyen’s support team ( firstname.lastname@example.org ).
- Intelligent failover: The terminal automatically will do a failover - even in an integrated set-up - to the 3G/4G network when it cannot reach the Adyen payment platform. There is some additional latency involved as it takes ~15 seconds to detect the main network failure during the first transaction. After 15 minutes the terminal will automatically try the main network interface again (this is configurable).
Connectivity is managed by Adyen globally, operating a global private APN cloud.
Your Adyen terminal can be configured to accept transactions offline, should Internet connectivity temporarily be unavailable. Offline transactions are riskier than online transactions. To protect against fraud, the terminals are configured with a floor limit. If the amount of the transaction is below the configured floor limit and the terminal cannot connect to the Adyen host for authorization the terminal will leave the decision up to the card to approve or decline the transaction, depending on the issuer. Debit cards will typically decline a transaction, while most credit cards are configured to approve low amounts offline.
Offline processing can impact reconciliation. Transactions may be sent in later or through a different flow. Ensure your bookkeeping system is adjusted to handle this automatically.

in-store staff send a direct link to the payment page in an email – with descriptions, payment amount, etc. already pre-filled. When constructing the email your system builds a link to a payment page just as would happen in your webshop. The shopper finalizes the transaction using their mobile as they would do with an e-commerce transaction. This option requires additional integration in the cash register to be able to send a payment link to the shoppers e-mail.
To be sure the shopper has successfully finished the transaction, you should sync your systems in real time. This avoids the possibility of a delay where the shopper walks out with the product without paying.
