Set up your payment terminals
Some sections of the terminal require a passcode to access. The 4-digit passcode for all terminals is 8588.
When your terminal arrives:
Connect the terminal to a power supply, then press and hold the power button until the screen turns on.
Let the battery charge for at least four hours while you continue the setup steps.
On the Welcome screen, select your language.
On the Setup Wi-Fi screen, tap the + sign.
Select your clinic's Wi-Fi network from the list, or tap + to enter the network name (SSID) manually.
Enter the Wi-Fi password, then tap OK.
The terminal connects to the network and displays a Wi-Fi icon at the top of the screen.
Your terminal is now ready to process payments.
Warning: If the terminal prompts you to select a store at any point during setup, stop immediately and contact [email protected] before continuing. |
Share IT network requirements with your team
If your clinic connects payment terminals to Wi-Fi, share the following requirements with your IT team or network administrator before go-live. Without these settings, terminals may revert to cellular or experience connectivity issues.
Your Wi-Fi network must support:
WPA/WPA2-Personal or WPA/WPA2-Enterprise encryption
2.4 GHz or 5 GHz frequency bands
A dedicated private wireless network for payment terminals (strongly recommended)
Wireless Isolation, AP Isolation, and Client Isolation must be disabled — these settings prevent terminals from communicating with the payment processor
Tip: Avoid connecting to a guest Wi-Fi network. Use a dedicated, low-traffic private channel for the most reliable payment processing. |
Your IT team must:
Add the following domains to your firewall's allowlist for outbound HTTPS traffic:
*.adyen.com
*.adyenpayments.com
Allowlist by domain name only — do not hard-code IP addresses, as these change and will break your connection
Open the following ports:
tcp/443 to the internet
tcp/8443 on your local network
Note: Your terminals include a built-in cellular backup. If Wi-Fi isn't configured correctly, the terminal may silently fall back to cellular, resulting in slower transactions or errors during cellular outages. Completing the steps above ensures terminals stay on Wi-Fi as intended. |
Frequently asked questions
What if my terminal falls back to cellular during a payment?
Cellular fallback does not recover a transaction already in progress. If your network drops mid-payment, restart the transaction. Contact your IT team to confirm the Adyen domains are on the firewall’s allowlist so the terminal stays on Wi-Fi.
