A smart payment terminal combines a modern Android operating system, an app ecosystem, advanced connectivity (Wi‑Fi, Bluetooth, LTE, QR‑camera), higher‑grade security (PCI PTS v6), and modular hardware that can be remotely managed and updated. A traditional terminal relies on a closed, proprietary OS, limited connectivity, fewer payment options, and static hardware—making it less flexible for today’s omnichannel and self‑service scenarios.
