Technical Transaction Flow

1. POS application → requests QR payment from eKasa
2. eKasa → contacts the FS notification server, obtains a unique payment identifier
3. QR code → generated based on the identifier, displayed/printed
4. Buyer → scans the QR code with their phone → bank automatically fills in payment details
5. Buyer’s bank → executes immediate payment to the seller’s account
6. Seller’s bank → sends confirmation to the notification server
7. eKasa → verifies payment via the notification server → prints receipt or rejection notice

For optimal integration

7. ⁠eKasa → verifies payment via the notification server → prints only payment receipt or rejection notice
8. ⁠once the POS application verifies the payment, it sends the cash register receipt to eKasa for printing

For simple integration

7. ⁠eKasa → verifies payment via the notification server → prints cash register receipt or rejection notice
