We have developed script licencing system PHP script, that allows you to remotely turn off or on all scripts you sold! Script works with unique generated activation codes that are different for any new installation - even on same URL! This is more than valuable protection against fraud orders that are chargebacked or refunded by third party payment processors with delay! Now you can allow your customers to download your scripts automatically - right after purchase! When customer installs a script for the first time, the script licensing system will notify you that your customer installed script and then you can allow/deny it! Script requires encryption of file where installation tracking script is implemented.
