PaynoPain POS Terminal User Guide: payments, transactions, refunds and reports Updated

Guide Sentinel V3.3.2

In this tutorial, we clearly and simply explain how payments work on PaynoPain physical POS devices through our payment application.

Throughout this guide, you will learn in detail about the main features of the tool, such as processing payments, viewing transaction history, managing refunds, and generating reports, among other key options for controlling daily operations.

Payment screen on the physical POS terminal

This screen is designed to make the payment process easier and faster, allowing key transaction details to be entered in a simple and intuitive way.

Main elements of the payment screen:

1. Numeric keypad: Used to enter the transaction amount.
2. “PAY” button: Once the total amount is entered, pressing this button starts the payment process.
3. Reference: This field is optional and depends on the device configuration. It allows you to enter a specific transaction reference (product or service name, order number, invoice number, etc.).

Payment result screen

When the payment process is completed, the device displays this screen, clearly showing the transaction result, whether approved, declined, or failed.

Main elements of the payment result screen:

1. Transaction details: Displays the amount and other relevant information such as status, date, encrypted card number, or reference.
2. “COPY” button: Allows printing a copy of the receipt for the customer, providing a physical proof of payment.

Transaction list

This screen provides a complete overview of the transaction history, allowing detailed and organized tracking of all business operations.

At the bottom of the screen, you will find arrows to navigate through the transaction list. You can use the page selector or navigation arrows to move through the records.

From the list itself, you can view general information such as transaction status and amount, exact date and time of the payment, reference (if entered), and Auth Code.

Searching by reference in the transaction list

At the top of the screen, in the “Search reference/authCode” box, you can quickly and accurately search for a transaction within the list, optimizing search time in the history.

How to search for a transaction?

Enter the reference in the search field and press the magnifying glass button on the keypad. To return to the full list, you can clear the filter by pressing the “X” icon.

Transaction filters

In addition to searching for transactions, you can filter them by transaction type (sales, refunds, pre-authorizations, confirmed), status (approved or declined), and sort them to facilitate analysis and organization.

In the upper left part of the screen, by pressing the filter icon, you can select filters and update the list with the corresponding results. Pressing the delete button resets the view by removing all applied filters.

Transaction details

When you click on a transaction in the list, a screen appears showing all the details of the selected operation.

This simple action improves business operations by providing clear and complete access to all relevant transaction information.

Refunds

By selecting a transaction from the list, you can process refunds for your business transactions.

To display the “REFUND” button, the refund option must be enabled in your device settings.

Transaction receipt

On the transaction details screen, you can also generate a receipt for the operation, either digital or physical.

Physical receipt

By pressing the receipt button located at the bottom left, you can print a physical receipt for either the customer or the business, depending on the need (payment proof or internal record).

Digital receipt via QR code

On the same transaction details screen, you can also generate a digital receipt via QR code, located at the bottom center.

By pressing the “QR” button, a QR code is created with the digital version of the receipt. You can show it directly to the customer so they can scan it with their mobile phone and save the digital receipt.

Digital receipt via email

On the transaction details screen, at the bottom right, there is an option to share the receipt digitally via email.

By pressing the “Email” button, a new window opens where you can enter an email address to send a copy of the digital receipt.

Refunds 

This feature allows you to manage refunds of previous transactions quickly and securely. The business can define the refund amount, either full or partial, adapting it to each case. The system always displays the maximum refundable amount, making operation control easier.

Once the amount is entered, you can confirm the operation to process the refund or cancel it to stop the process. To complete the refund, the operation must be confirmed so it is properly recorded.

Reports on the device

This feature allows you to generate summary reports of transactions directly from the device. The screen displays key data such as totals, sales, and refunds.

It is also possible to generate reports with all transactions recorded up to the current date. For subsequent reports, the system automatically sets the start date as the last generated report, enabling continuous activity tracking.

Cash closure confirmation

When pressing the cash closure button, all reports displayed on the screen are printed.

Before finalizing the process, you must confirm the operation. It is recommended to review all generated data beforehand to ensure accuracy before accepting.

Physical POS settings

This section contains all available application configurations and some system settings.

In this area, you can manage different functions: enable payments, pre-authorizations, tokenized payments, references, access reports, and other features.

The payment application is fully configurable, so only previously enabled features are shown as active.
