Nano Gates

This is a for nano-currency.

A pay-gate is similar to a pay-wall, with one key difference. A pay-wall requires everyone to pay for access. A pay-gate gives everyone access for a limited time, as long as a payment has been made. Just like a gate in real life - when it is closed, no one gets in. When it's open, everyone can come in.

You can see a demo and instructions below.
