Registeration Key after every 30 days

I have a scenario and bit confused that how can I achieve it. I have implemented in my application basic trial feature based on days. Actually I am charging my clients per month basis so what I need to achieve is that if the customer has bought the licence of 30 days then fine the application should run for upto 30 days but after that 30 days if the customer has not renewed the license I want to show him again a Message that License expire please enter new license key and until the customer enters the new valid code the application should not run.
How can I achieve this.
