For now, the application is available only for Android OS v.9.0 or later version.

Before you start using the Application, make sure that:

• your device is running Android OS v. 9.0 or higher
• the device has an installed NFC module
• the device has the Google Play Store application installed.

These are the minimum requirements for installing the Application. However, after the Application is installed, the program checks the reliability of your device. If the state of your device does not meet the security criteria, further use of the Application can be restricted.

Activation codes for the “tapXphone” Application are sent to the email as soon as you start the activation process on your mobile device. 
The activation code is sent by email (which is mainly specified in the Application for the Payment card Acceptance Contract and the Card Acceptance Device (POS terminal) Rental Contract).

There may be several possibilities for such a situation to occur:

1. If you have already activated the payment terminal and replaced the default password for the one of your own, make sure that you enter it.
2. If there is another cashier who also uses this device, with the same credentials, please check whether he/she has changed the password.
3. If you forgot the password that you set after activating the application, return the default password in the Merchant's portal. The details are in Merchant portal User Guide > Resetting the Password for the Application.
4. If your device is already linked to another Merchant (their payment terminal) and is used by them. In this case, you need to disconnect the device from the payment terminal of the "old" Merchant. This feature is available in the Merchant's  portal under the account of the "old" Merchant. For more information go to the Merchat portal User Guide > Payment Terminal unbinding.

Initialization is a process that provides for downloading the necessary settings to your device, which will allow you to use the “tapXphone” Applications in the future.If your device is suspected not meet the Security Criteria, the application may re-request the initialization process For more information go to the Merchat portal User Guide > Payment Terminal unbinding.

The password received in the email is used to log in to the Merchant's web portal, not to log in to the “tapXphone” application.
If this is the first login to the “tapXphone” Application, then the default Password is your Login (case sensitive). What is used as a Login in your situation is determined by Citadele bank.

It is possible that the characteristics of your device do not meet the requirements for installing the Application. Make sure that:

• your device is running Android OS v. 10.0 or higher
• the device has an installed NFC module
• the location of your Google ID is the same as your region.

We can assume that in the application to the Citadele bank you requested only one payment terminal, respectively, your second device cannot activate a payment terminal that does not exist (all are already activated and linked to other devices).
To "move" the payment terminal onto another smartphone, you should unbind the old smartphone from the terminal. This feature is available in the Merchant's portal. For more information, go to the Merchat portal User guide > Payment Terminal unbinding.

The application can only be installed once per device.
After entering your login details, you will be notified that an incorrect username or password has been entered. In this case, you will have to disconnect the device from the respective merchant (payment terminal) each time and assign the existing device to another merchant's payment terminal. More information in Merchat portal User Guide > Payment Terminal unbinding.

You can download the app from the „Google Play“ Store - enter the keywords "Citadele Phone POS" as well as "tapXphone" in the search field. For now, the application is available only for Android OS v.9.0 or later version.

The connecting and activation codes are sent by the system to the Merchant's email address, which is specified in the Application for the Payment card Acceptance Contract and the Card Acceptance Device (POS terminal) Rental Contract. Check if this Email address is the same as one you are using on your device at the moment.

To enter the PIN code securely, a virtual keypad is used, the buttons of which are arranged in a random order and are of different sizes. The purpose of this decision is to protect the payment card holder that his PIN will not be recognized.

1. Make sure that the card has a contactless payment feature(marked with an icon)
2. Make sure the NFC model is turned on on the device.
3. Make sure that the card is touched to the location of the NFC module of your device. For more information, go to the App “tapXphone” User Guide > Payment acceptance. 
4. Perhaps the case on your device blocks the signal of your NFC antenna, so remove it and repeat the operation
5. Make sure that the card is not removed from the field of reading of the NFC module too quickly.
6. Perhaps the antenna of the card itself is damaged (this is not a rare case, so you can check with the client how their card works on other payment terminals)
7. The NFC module may be damaged. You can try installing a third-party application designed to read NFC tags (for example, like this), and test the operation of your NFC with the help this application. 
    

In the Application, you can only see the operations of the current (not closed) business day performed on a specific device. In the Merchant's portal, you can see all transactions for any period of interest and for any device, print out reports, track and change the status of your cashiers, disconnect mobile device from one payment terminal and assign to  another device.
