SoftPOS works by installing a certified payment‑processing app on a regular smartphone or tablet. The app uses the device’s built‑in NFC antenna, camera, or QR‑code scanner to read card data or mobile‑wallet credentials. Once the card information is captured, the app encrypts it and transmits it over a secure TLS connection to the merchant’s acquiring bank or payment gateway, which authorises the transaction in real time. The solution complies with PCI‑DSS and EMV standards, so the device functions as a fully secure point‑of‑sale terminal without any additional hardware, enabling quick, low‑cost deployment for merchants of any size.
