In app/assets/config/user.js, edit the payment terminal by specifying:
```
    devices : {
        payment_terminal_module : 'adyenDevice'
    },
```
Ensure that tiapp.xml file is based on the tiapp.xml.sample.adyen file.
On the VX680, do the following:
1. Press green key + 5 at the same time.
2. Get the IP address.
Board the Adyen device:

2. Start the Endless Aisle app on the device on which you intend to run it in the store.
3. Tap the Hamburger Menu and tap Admin Dashboard.

The Adyen device tells the Endless Aisle app if the signature is needed; the app shows a dialog. After the signature is provided by the customer, there is the option for the associate to approve the signature. The required setting is in the Endless Aisle Checkout preference; the option is Adyen Signature Confirmation. See Setting Up Endless Aisle Checkout.
During testing, you can copy "allow_simulate_payment": false from app/assets/config/main.js to app/assets/config/user.js and set it to true, however, you set this to false before deploying the app. You can use the iPad simulator with the Adyen device if using Ethernet connection.
