Troubleshooting guide

MultiSafepay POS solutions

Resolve common issues when using SmartPOS or Tap to Pay.

Common scenarios

Initial setup & Activation

Problems that occur during the initial setup and activation of your device.

The "Point of Sale" section is not visible in your Merchant Dashboard

If you cannot access Point of Sale > Terminals from your dashboard, your user account may not have the required permissions.

You can:

  • Check if your user has the correct permissions, or contact your administrator.
  • Email [email protected] to contact us.

"IPEK not configured" message appears

The Initial PIN Encrypted Key (IPEK) is not been registered on your device.

If your IPEK is not configured, try to configure it manually first:

  1. Go to your device's Android Settings > System.
  2. Go to Advanced > Security Center.
  3. Click Key Inject. Go to RKI and click Key Inject.
  4. Once the process finalizes, click Confirm.

If manual configuration fails:

Activation fails with "Server error (10008)"

If you try to activate a device before it has been fully synchronized, an error might occur.

To fix this:

  1. Turn off the device. Wait 10 seconds and turn it back on.
  2. Connect to a stable internet connection (Wi-Fi or cable).
  3. Follow the activation process.

Make sure that:

  • Your internet connection is not restricting correct synchronization (e.g., firewall, proxy).

  • For SmartPOS, the device is fully synced with Sunmi before attempting activation.

Connection & Network

Issues related to your device's internet connection.

The internet connection is unstable or disconnected

Follow these steps:

  1. Check your router: Ensure your Wi-Fi router is on, connected to the internet, and the network is stable.
  2. Check the connection icon: If you are connected, check the color of the internet icon on your device's status bar.

The network connection is good.

The device isn't connected and isn't working correctly.

For SmartPOS:

  • Verify the device is connected to Wi-Fi or Ethernet.
  • For P2 Smartpad, verify the network cable is connected correctly.

For Tap to Pay:

  • Verify Wi-Fi or mobile data is enabled.

  • Test the connection by opening a website.

  • Switch between Wi-Fi and mobile data if available.

Payment Processing Errors

Problems that occur when processing payments.

An order is placed, but it doesn't appear on the device

Make sure that:

A payment is declined

If a payment is declined, check the error message on the screen and find the solution below.

Additional Check: Ensure that you have not accidentally deactivated any card payment methods in your MultiSafepay dashboard.

Understanding "Soft Declines"

You may receive a "declined" status during a transaction. This is a soft decline. It occurs when a customer needs to take an extra step (like entering a PIN for a large amount).

You will first receive a declined notification, but once the customer completes the action, you will receive a final status of completed or cancelled.

⚠️

Note:

Do not treat a soft decline as a final payment status. Wait for a final completed or cancelled status.

Display and app behavior

Problems with how information is displayed on the screen or how apps are behaving.

The group logo is not being displayed in Cloud mode

Try to:

  1. Go to Android Settings > Apps & Notifications.

Hardware

Issues related to the physical device.

System Alarms

A Tampering alarm is displayed

If your device is blocked and shows an error like "Attacked! Please contact your service provider" or "Alerts triggered! Please contact your service provider" this might be due to device being damaged (e.g. the device falls on the ground). Follow these steps, in case the errors are shown:

Traditional (CTAP) terminal

Activation

The "Devices" section is not visible in your Merchant Dashboard

Your user account may not have the required permissions.

Try to:

  • Check if your user has the correct permissions, or contact your administrator.

  • Email [email protected] to contact us.

Connection and Network

The internet connection is unstable or disconnected

Follow these steps:

  1. Check your router: Ensure your Wi-Fi router is on, connected to the internet, and the network is stable.

  2. Reconnect to Wi-Fi: If the terminal is disconnected, follow the steps to connect to your Wi-Fi network.

Payment errors

If you are experiencing any issues related to payment processing, check if:

  • The terminal connected to the internet. See Connection and Network.
  • Your terminal is activated in your Merchant Dashboard.

Duplicate order_id in test transactions

Some C-TAP test applications, such as those on CCV terminals, reuse a default order_id when creating transactions. Because MultiSafepay does not allow duplicate order_id values, subsequent transactions may fail.

To avoid this issue, use the LIVE payment application when testing payments. If you must use a terminal's test application, ensure that every transaction uses a unique order_id.

⚠️

Note

MultiSafepay does not provide a test environment for POS payments. All terminal transactions are processed in the LIVE environment, including those initiated from a terminal's test application.

Contact your provider

If your issue is related to hardware malfunctioning or if you can't find a solution in our troubleshooting page, contact your provider for further assistance.
