FAQs
Q1: What does it mean for a device to be payment-enabled?
It means the device can securely process and complete transactions on its own - without needing to connect to a central server in real time. Payments are handled locally (at the “edge”), ensuring speed and reliability.
Q2: Why enable payments on devices?
Enabling on-device payments reduces friction, improves customer experience, supports offline transactions, enhances security, and lowers infrastructure costs. It also unlocks new business models and revenue streams.
Q3: What types of devices can be payment-enabled?
Vending machines, transit gates, parking meters, EV charging stations, self-service kiosks, wearables, connected vehicles, and many other IoT devices can all be payment-enabled.
Q4: How secure are edge-based payments?
Highly secure. Transactions use secure elements, encryption, and local authentication (like biometrics). Sensitive payment data doesn’t need to travel to the cloud in real time, reducing exposure to breaches.
Q5: Can these devices work offline?
Yes! Edge payment systems can process transactions locally, store them securely, and sync with central systems when connectivity is restored. This makes them ideal for areas with unreliable internet.
Q6: How do payments sync with central systems?
Transactions are securely queued on the device and then batch-synced to central servers for settlement and reconciliation when a connection is available.
Q7: What industries benefit most?
Retail, mobility, transit, smart cities, automotive, vending, and any sector that needs fast, reliable, unattended payments benefit from edge-enabled payments.
Q8: How hard is it to integrate?
Our solutions are designed for easy integration with SDKs, APIs, and developer-friendly tools, making it simple to enable payments on your devices.
Q9: What payment methods are supported?
We support a wide range of payment technologies including NFC, QR codes, sound-based payments, and other proximity-based solutions.
