Acquirers and ISVs should offer SoftPOS when the priority is speed, cost‑efficiency, mobility, and easy integration—especially for long‑tail merchants, vertical‑specific use cases (hospitality, delivery, pop‑up retail), and when a bank/PSP can use its brand to mitigate security concerns. For high‑volume, fixed‑location stores that need maximum reliability and throughput, a traditional terminal remains the better choice.
