webPOS 4.0

Integration with

Payment Terminals

Direct communication between WebPOS and the terminal

Our WebPOS system enables direct integration with payment terminals, making the transaction process faster, simpler, and more secure. The cashier no longer needs to manually enter the amount on the terminal — the system automatically transfers the transaction value, and the terminal immediately displays the amount to the customer.

This significantly reduces the risk of payment errors, while the entire sales process runs more smoothly.

How does
the integration work?

Payment method selection – the cashier chooses card payment in WebPOS.
Automatic transfer of the amount – the system sends the transaction value directly to the terminal.
Payment authorization – the customer confirms the transaction on the terminal.
Confirmation – after payment is accepted, the terminal sends the status back to WebPOS.
Fiscalization – only after the payment is confirmed does the system automatically fiscalize the transaction and print the receipt.

This approach eliminates situations where a receipt would be printed despite a declined payment.

Supported operators

Our system provides proven integration with the largest payment operators on the market:

PeP (Polskie ePłatności)

Integration with payment terminals in WebPOS guarantees efficient and error-free payment processing. Thanks to direct communication with the terminal, we eliminate the risk of discrepancies between the receipt amount and the actual paid amount. The system fiscalizes sales only after receiving payment confirmation, which increases security and ensures transaction compliance.

The solution supports the largest operators on the market and is fully scalable – suitable for both a single point of sale and large retail chains.
