Hello, I can integrate Square Terminal with your Floreant POS so that each closed ticket automatically sends the total to the terminal, runs a full tap/chip/swipe flow, and returns the approval/decline result back to mark the ticket as Paid (Square) with the transaction ID stored. I work with Java-based POS systems and payment APIs, so I can implement this as a Floreant plugin or small middleware layer that also supports refunds, cancellations, partial payments, and robust retry logic if the terminal disconnects—without ever touching raw card data, fully aligned with Square’s PCI-compliant model. I’ll set everything up in your Windows restaurant environment (multiple stations), provide clear setup instructions, and walk through sample test transactions so your team can operate and maintain it confidently. Best regards, Juan
