Android POS combines an open Android ecosystem with rigorous, PCI‑validated hardening: the device runs a locked‑down, signed‑boot OS that protects against tampering, while every third‑party app is scanned for vulnerabilities and must meet bank‑security requirements before being signed and deployed. Centralised management through Ingenico 360 delivers OTA security patches, remote monitoring and policy enforcement across the entire fleet, ensuring that the flexibility of installing new payment or loyalty apps never compromises enterprise‑grade security.
