At ISN Free WiFi, we saw this gap and developed a solution that business owners will truly appreciate. Instead of relying on a shared password, our system introduces Voucher Presets with full API integration. This means your point‑of‑sale system can automatically print a secure voucher PIN on a customer’s receipt. Each voucher is unique, cannot be reused, and is fully customizable in the ISN dashboard, you decide how many devices it supports, how long it lasts, and other settings. Employees no longer need to manage passwords manually, and customers receive a seamless, secure way to connect.
This approach directly solves the problem of password sharing. A voucher is tied to a purchase and cannot simply be passed around to outsiders. It enforces fairness: only those who buy from your business gain access to the WiFi. The result is a faster, more reliable network for genuine customers, and peace of mind for business owners who want to protect both their bandwidth and their bottom line.
