Device Setup 

The AMS1 functions as an all-in-one terminal running on the Android platform. This mobile, cellular device offers seamless connectivity with the Flash Valet app through either Wi-Fi or 4G cellular data.

Internet Connection Setup

  1. On the Adyen device tap the Settings icon from the home screen.
  2. Network > Enter passcode 6006 > Continue > Wi-Fi > Connect to your Network.
    • To connect to cellular, do the same as above but tap on Cellular. 

Flash Valet app Connection

On the Flash Valet app, go to the Control tab > Settings.

  • Tap Use Adyen Card Reader.
  • After tapping on the Serial number, return to Settings and confirm the connection: The AMSI Device Name will match the S/N number on the back of the AMS1 device and show its battery level.

Network Connectivity Troubleshooting 

Should a network connection issue arise, the AMS1 promptly attempts to auto-connect within a few seconds. In the event of persistent issues, operators can initiate a manual restart by holding the power button on the right and selecting the Restart option. For Wi-Fi network changes, a passcode "6006" is used to access the Connect feature, enabling operators to select a different Wi-Fi network if required.

Cellular 3G/4G failover

If the Wifi internet connection fails, your AMS1 terminal can automatically switch to processing payments using a cellular connection. Adyen terminals come with a pre-installed and activated SIM card so you can use the cellular network immediately to board the terminal.

How it works

Payment process

  1. Tap the Credit Card tender type option in the Flash Valet app when processing a payment.
  2. Present Card Payment Process:
    • The Flash Valet app will display the message "Please Swipe, Insert or Tap" on the AMS1 terminal's screen.
    • The AMS1 terminal will automatically light up* and display the Amount Due, prompting the customer to present their credit card.
  3. Tips Collection (If Applicable):
    • If credit card tips are enabled, the customer will see the Original Amount Due and can choose a tip amount. 
    • The customer finalizes their decision before proceeding with the payment.

  • Payment Cancellation Option:
    • Customers have the option to cancel the payment at any time by tapping the X in the upper right corner on the AMS1 terminal.
    • If the payment is canceled, the Flash Valet app will show "Transaction canceled."
  • Restarting Payment Process:
    • When the customer is ready to proceed, the valet taps "Present Card" in the Flash Valet app to restart the payment process.
  • Automatic Transaction Cancellation:
    • If a credit card is not used within about three minutes, the transaction will auto-cancel on the AMS1 terminal.
  • Waking Up the AMS1:
    • Even if the AMS1 terminal is asleep, selecting the "Credit Card" tender type in the Flash Valet app will automatically wake it up; there is no need to wake it up manually (pressing power button on right side).
